Engaging in online arbitrage on Amazon can be a profitable business. To succeed as an online arbitrage seller, it is crucial to find the right products. These are in-demand items with profit potential.

However, searching for profitable online arbitrage products can be time-consuming. That's why Amazon product research tools are essential. These tools help sellers make smart decisions based on data.

This guide shows how to find profitable online arbitrage products using the best product research tool — Seller Assistant App. This tool lets you save time, uncover high-profit opportunities, and make informed choices to succeed as an online arbitrage seller.

How to Do Online Arbitrage on Amazon?

To successfully start and develop an online arbitrage business, you must find cheap products to resell on Amazon with a profit margin.

This task includes two parts. Firstly, you must identify profitable products that are in demand on Amazon. Secondly, you must find a supplier for that product who sells it much cheaper than its sale price on Amazon so that you can get a profit from sales.

The first one, finding products for reselling, is achieved through product research. Usually, sellers use product research tools to simplify and speed up this complicated process.

Once you have identified a potentially profitable product to sell on Amazon, the next step is to find product suppliers.

Below we will describe how to find products for online arbitrage and ensure they will not trigger problems when you sell them. We will also show a simple way to find product suppliers.

How to Find Online Arbitrage Products?

Sourcing profitable OA products involves doing product research to select products that fit your specific criteria, like profitability, sales velocity, profit margin, etc. To identify such items quickly, you can use product research software.

The best online arbitrage tool for product research is Seller Assistant App, a popular all-in-one product research extension. This handy tool displays important product metrics right on Amazon's product and search pages. That lets you quickly access all the essential information about a product in one convenient place.

Online Arbitrage with Seller Assistant App Step-by-step

Step 1. Exclude private label and sold by Amazon products

To start, make sure the product is not a Private Label (PL) item. You can’t sell these products because another merchant trademarks them.

To identify PL items, use the number of sellers as a clue. If only one seller is listed on the Seller Assistant App's Product Information dashboard in the FBA and FBM fields, it's likely a Private Label product. Avoid buying it.

Also, check if Amazon sells the product and avoid competing with them. That is a challenging task.

Step 2. Check product sales

Assess the product's demand by looking at its Best Sellers Rank (BSR) on Amazon. Although exact sales figures aren't provided, BSR gives you an idea of sales performance.

Seller Assistant App can provide an estimated sales number based on BSR and category. It also shows the average BSR and its history over 30, 90, and 180 days.

Look for high-performing products highlighted in green (top 1% of sales), and be cautious of lower-performing products marked in red. Pay attention to the arrows—the green downward arrow indicates a decrease in BSR, while the red upward arrow indicates an increase.

Step 3. Check Buy Box information

Evaluate your competition by examining the Buy Box seller's offer.

Seller Assistant App provides essential Buy Box details, including the average Buy Box price and minimum FBA and FBM Buy Box price offers. Consider the dynamics of the Buy Box, especially price changes that could affect your ability to sell consistently.

Step 4. Analyze competition and potential sales

Estimate the level of competition and potential sales volume.

Seller Assistant App shows estimated potential sales if you become an additional seller.

Take note of the number of merchants selling the product, with over 10 FBA merchants indicating high competition. Identify competitors who offer prices 2-3% higher than the Buy Box price and set your price accordingly.

Step 5. Verify sales restrictions and alerts

Ensure the product is not in a restricted category or brand and won't create any issues. Use Seller Assistant App's features like IP Alert and Restriction Checker.

The IP Alert feature displays a Red Triangle icon if there have been past issues with the product.

Seller Assistant App's IP Alert

The Restriction Checker feature indicates your eligibility to sell the product with a Green Open Lock or Red Closed Lock icon. Pay attention to warnings for IP alerts, restricted products, oversize products, meltable products, hazardous material categories, and adult products.

Note. You can also use Seller Assistant App’s free online arbitrage software IP Warning to identify products with intellectual property claims.

Step 6: Check product profitability

Evaluate the product's profitability by calculating essential metrics. Seller Assistant App's FBA&FBM calculator can help with this.

Consider costs like FBA or FBM fees, Amazon commissions, referral fees, storage costs, third-party logistics expenses, and shipping costs.

Step 7. Save the result to Google Sheets

Export your product research results to Google Sheets for further storage and analysis. On the Amazon website, open a product, add any necessary notes, and click the "Save" button to save the results.

How to Find OA Product Supplier?

After you select a product to resell, you must find a supplier for it. The supplier’s price must be low so that you can get maximum profit.

To find a supplier, you can also use Seller Assistant App.

Once you select a supplier from the drop-down list, you will be automatically redirected to the search results page for that specific product on the chosen platform. That allows you to explore and select the supplier.


In conclusion, finding online profitable arbitrage products can be challenging. Leveraging seller tools simplifies product research, helping you identify profitable opportunities and make informed decisions.
