Online Arbitrage for Beginners

If you’re new to selling on Amazon, online arbitrage is a great way to start making money with minimal risk and investment. In this business model you buy discounted products online and resell them for a profit on Amazon. According to Jungle Scout, 21% of Amazon sellers use online arbitrage, making it one of the most popular methods to start an Amazon business.

Why is online arbitrage so attractive to beginners? Unlike private label or wholesale, it doesn’t require a big upfront budget, and you can test the waters without committing to a large inventory. With the right strategy and product research, even small purchases can turn into steady profits.

In this guide, we’ll cover everything you need to know about online arbitrage for beginners, from key terms to sourcing strategies and pricing tips.

What Is Online Arbitrage?

Online Arbitrage (OA) is a business model where sellers buy discounted or underpriced products from online retailers and resell them on Amazon for a profit. The key idea is price difference – finding products that are cheaper on one platform and selling them at a higher price on another.

This model is popular among beginners because it requires low upfront investment and no need for brand creation or manufacturing. Unlike wholesale, where you buy in bulk from suppliers, OA allows you to start small and scale up over time.

The big idea behind online arbitrage

Online Arbitrage is about finding cheap products, reselling at a higher price, and pocketing the profit.

Sellers use product sourcing software tools (such as Seller Assistant) to choose best-selling and high-margin deals, estimate demand, and calculate profitability before purchasing products.

Online arbitrage works because of market price differences – retailers may offer discounts, clearance deals, or regional pricing deviations, creating opportunities for resellers to profit on Amazon’s marketplace.

With the right research and sourcing strategies, anyone can turn online arbitrage into a profitable Amazon business.

How is profit generated?

Profit in online arbitrage comes from the difference between the buying price and the selling price, after accounting for Amazon fees and shipping costs. The formula looks like this:

Profit = Selling Price - (Cost of Goods + Amazon Fees + Other Expenses)

To maximize profit, sellers look for products with:

• High demand

Consistent sales on Amazon

• Moderate competition

Not too many sellers on the listing

• Good profit margins

After all costs, the product still brings a decent return.

Real-world example of online arbitrage in action

Let’s say you find a LEGO set on Walmart’s website for $30 during a clearance sale. You check Amazon, and the same set is selling for $60.

Step-by-step process

• Buy the product

Purchase the LEGO set from Walmart for $30.

• List on Amazon

Create a listing or add to an existing one.

• Calculate fees

Amazon takes $10 in fees (FBA fulfillment, referral fee, etc.).

• Ship to Amazon

If using FBA (Fulfillment by Amazon), you send the product to their warehouse.

• Sell for a profit

When the product sells for $60, Amazon deducts fees, and you are left with:

• Selling price: $60
• Amazon fees: -$10
• Cost of goods: -$30
• Total profit: $20
• ROI: 66% ($20 profit ÷ $30 cost x 100).

Key Points to Remember about Online Arbitrage

Online arbitrage can be a profitable and low-risk way to start selling on Amazon, but success depends on making the right decisions. Here are the key insights every beginner should keep in mind.

Winning product is key

Choosing high-demand, low-competition products is crucial. Avoid restricted or flagged items to prevent listing issues and unnecessary risks.

Product research takes time but is essential

Finding profitable products requires thorough research, and it can be time-consuming. However, tools like Seller Assistant can speed up the process and help you make data-driven decisions.

Use discounts and cashback to lower costs

Successful OA sellers use every possible way to lower costs, including discounts, cashback, coupons, gift cards, and credit card rewards. Stacking these savings can reduce product costs by up to 20%, increasing your profit margins.

Competition can impact profits

Since many sellers target the same products, prices can fluctuate, and profit margins may decrease over time. Staying ahead requires consistent research and a good sourcing strategy.

Check for restrictions and potential risks

Always verify whether a product is restricted or requires approval on your Amazon seller account. Also, check for potential risks, such as IP complaints, Amazon policy violations, fragile or meltable items, to avoid extra costs and selling issues.

Starting costs are low, but scaling takes time

You can start with as little as $500, making online arbitrage one of the most affordable ways to begin selling on Amazon. However, scaling up takes time, effort, and reinvestment of profits.

OA is easy to start but requires consistency

Setting up an Amazon seller account and sourcing products can be done quickly, but consistent effort is needed to find profitable deals and manage inventory efficiently.

How Does Online Arbitrage Work?

Online arbitrage is an easy-to-start but strategic way to make money on Amazon. The process involves finding discounted products online, reselling them at a higher price on Amazon, and earning a profit. Success depends on smart product selection, accurate research, and effective pricing strategies. Here’s a step-by-step breakdown of how it works.

Steps to online arbitrage

Step 1. Create an Amazon seller account

Start by registering as an Amazon seller. Choose between:

• Individual plan (for casual sellers)

Best for those selling fewer than 40 units per month.

• Professional plan (for bigger-volume sellers)

Choose it if you plan to sell more than 40 units per month.

You’ll need to provide your business details, tax information, and payment method. Once registered, you’ll gain access to Amazon Seller Central, where you manage your sales, inventory, and orders.

Step 2. Find potential deals

Look for products where the price is significantly lower on supplier websites than on Amazon. There are multiple ways to do this:

• Manually search for single products on retail websites.
• Parse supplier websites and use product sourcing tools like Seller Assistant’s Price List Analyzer to automate deal-finding.
• Sell best-sellers already performing well on Amazon using Seller Assistant’s Seller Spy.
• Hire a virtual assistant to research deals for you.
• Pay for lead lists to save time on research.

Step 3. Do product research

Once you find potential products, analyze their profitability and demand to avoid bad purchases. Use tools like Seller Assistant to check:

• Whether you can sell the product on your Amazon account.
• Profitability after Amazon fees and shipping costs.
• Sales trends and competition.
• Potential risks, such as IP complaints, Amazon policy violations, and alerts (hazmat, meltable, etc.)
• Skipping this step can lead to low sales, losses, or account issues, so research thoroughly before purchasing.

Step 4. Decide how many products to buy

Base your purchase quantity on demand forecasts and budget. Use Seller Assistant’s Sales Estimator and other features to estimate how many products you can sell monthly. Beginners should start small and scale gradually to avoid overstocking and tying up capital in slow-moving inventory.

Step 5. Source products

Once you’ve decided what to buy, purchase products from online retailers. To increase profitability, take advantage of:

• Discounts from sales and promotions.
• Cashback offers and rebate programs.
• Coupons, gift cards, and credit card rewards.
• New user discounts from supplier websites.
• By stacking these savings, you can reduce costs by up to 20%, improving your margins.

Step 6. List products on Amazon

Add your products to Amazon’s catalog by either:

• Joining an existing listing (if the product is already on Amazon).
• Creating a new listing (only if the product does not exist in Amazon’s catalog).
• Amazon does not allow duplicate listings, so always check before creating a new one.

Step 7. Choose a fulfillment method

Decide how you will deliver products to customers:

• Fulfillment by Amazon (FBA)

Amazon stores, packs, ships, and handles customer service for a fee.

• Fulfillment by Merchant (FBM)

You store and ship products yourself.

While FBA is more convenient, it comes with multiple fees, so be sure to calculate profitability carefully before choosing your fulfillment method.

Step 8. Set competitive pricing

Price your products strategically to win the featured offer (Buy Box) and stay competitive. Use repricing tools to automatically adjust prices based on market changes.

• Consider your break-even point (BEP) to avoid selling at a loss.
• Choose a repricing strategy that balances profit and competitiveness.

Step 9. Monitor performance and scale your business

Success in online arbitrage requires constant optimization. Regularly track:

• Sales performance and profit margins.
• Customer feedback and reviews.
• Inventory levels to avoid stockouts or overstocking.

As you gain experience, scale your business by increasing inventory, expanding your product selection, and investing in automation tools to streamline sourcing and pricing.

Where to Find Online Arbitrage Products for Amazon?

Finding profitable products is the key to success in online arbitrage. There are several strategies sellers use to source inventory, each with its own benefits. Below, we explore the most effective ways to find products, along with tips on how to research them properly.

Strategy 1. Find deals yourself

• What it is

This strategy involves manually searching for individual deals where there is a clear price difference between the supplier's price (lower) and Amazon's price (higher). It’s best suited for sellers who prefer a hands-on approach to product selection. However, it can be very time-consuming, making it difficult to find many deals quickly.

• What is achieved

By using this method, sellers can hand-pick high-quality, low-risk products and develop a deep understanding of market trends. Since it's a manual process, there is more control over the products selected.

• How it works

Search for popular, low-risk products manually on retail websites. 

• Use Seller Assistant’s Quick View to quickly analyze product demand and risks on Amazon  search pages

• Open popular products and find their match at the supplier with Lookup Links feature

• Use Side Panel View to calculate deal profitability on the supplier website, side-by-side.

Strategy 2. Parse and automatically scan supplier lists

• What it is

This strategy uses automation tools to scan bulk supplier product lists, allowing sellers to analyze a large number of products efficiently. It is perfect for sellers managing a large inventory who need to quickly filter through thousands of products.

• What is achieved

Sellers can save time by automatically filtering high-margin, low-risk products from supplier catalogs. This method also reduces costly sourcing mistakes by flagging restrictions, high competition, or pricing issues in advance.

• How it works

Use Seller Assistant's Price List Analyzer to upload and scan a supplier’s price list

• The tool automatically matches products to Amazon listings, calculates profitability, and flags potential risks like gated products, too high ROI, hazmat, meltable, etc. You can configure the sheet and filter results.

• Sellers can quickly identify the most profitable opportunities without manual searching.

How to research effectively

• Sales performance

Check Best Sellers Rank (BSR) to verify demand.

• Competition level

Avoid listings with more than 15 sellers or those dominated by Amazon.

• Buy Box chances

Identify who controls the Buy Box and if you can compete.

• Pricing and profitability

Ensure ROI and profit margins meet your business goals.

• Restrictions

Verify product restrictions, selling eligibility, IP complaints and Amazon policy violations.

Strategy 3. Research your competitors to sell what they sell

• What it is

Competitor research involves analyzing successful Amazon sellers to discover the products they are selling. This allows sellers to capitalize on proven deals and avoid the guesswork of product selection.

• What is achieved

By identifying top-performing products and brands, sellers can increase their chances of success by offering similar or identical items. This method helps sellers focus on high-demand, profitable products.

• How it works

Use Seller Assistant’s Seller Spy to automate tracking competitor stores.

• Analyze what products they sell, what they have recently added or removed, and their pricing strategies.
• Identify best-selling deals to build a similar product portfolio.

How to research effectively

• New product monitoring
• Track what competitors are adding to stay ahead of trends.
• Product removals
• Identify items competitors stop selling to avoid slow-moving inventory.
• Seller feedback
• Analyze competitor product ratings and customer reviews.
• Pricing strategies
• Monitor competitor pricing to stay competitive and optimize profits.

Strategy 4. Hire a Virtual Assistant

• What it is

A virtual assistant (VA) is someone hired to find product deals on behalf of the seller. VAs can handle the time-consuming process of deal searching, allowing sellers to focus on scaling their business.

Strategy 5. Buy leads lists

• What it is

A leads list is a pre-researched collection of profitable product deals that sellers can purchase. These lists contain ready-to-buy products that have already been analyzed for profitability, competition, and demand.

How to Do Product Research for Online Arbitrage?

Finding the right products is essential for making money with online arbitrage. Not every trending item is profitable – successful sellers analyze key product metrics before investing in inventory. 

A truly profitable Amazon product should

• Sell well (high demand and fast turnover)
• Be profitable (high ROI and margin after fees)
• Carry minimal risks (you must be able to sell it, no IP complaints, or alerts and hidden costs)

Using Seller Assistant, sellers can streamline product research and make data-driven decisions. Below are the step-by-step guidelines to help you find winning products on Amazon.

Online arbitrage product research step-by-step

Step 1. Set up your Amazon search for accurate results

To ensure accurate research, configure your Amazon settings before searching for products.

✅ How to do it

• In the “Deliver to” field, enter the country and zip code where you plan to sell. This ensures Amazon displays the correct FBA and FBM offers available in that region.

• Ensure the product link doesn’t contain a referral to prevent incorrect listing data (e.g., missing variations or incorrect seller counts).
• Remove the referral part of the link by clicking the ASIN in Seller Assistant. This will reveal all variations that might not be visible with the referral link.

Why this step is necessary

Setting up your search correctly ensures you get accurate listing data, avoiding mistakes in product research.

Step 2. Check if you can sell the product

Before researching further, confirm that you are eligible to sell the product. Amazon restricts certain categories, brands, and products based on your seller account status.

✅ How to check using Seller Assistant

Use Seller Assistant's Restriction Checker.

A green open lock means you can sell the product.

A red closed lock means the product is restricted. Click it to to check whether you can ungate the product.

• Enter ASIN number, select the “new” condition, and fill in the form to request approval. Then, you can sell the product.

• If you can’t sell a product on your  amazon
