Online Arbitrage

If you’re selling on Amazon—or thinking about starting—it won’t be long before you hear the term “arbitrage.” One of the most accessible and beginner-friendly ways to launch your e-commerce journey is through a method known as online arbitrage.

But what is it, exactly? And how can you start profiting from it right at home?


Let’s break it all down.



🛒 What Is Online Arbitrage?

Online arbitrage (OA) is the process of purchasing products at a lower price from one online retailer and reselling those items at a higher price on a different platform—like Amazon, eBay, or Facebook Marketplace.

You're essentially flipping products for a profit using the price difference between two marketplaces. For example: You find a toy on Walmart.com for $5, and it's selling for $20 on Amazon. You buy it, list it, and profit after fees.


No need to leave your house, visit store after store, or worry about parking and crowds. With online arbitrage, all your product sourcing is done behind a screen.



🆚 Online Arbitrage vs. Retail Arbitrage

Both strategies revolve around buying low and selling high. The difference?

  • Retail arbitrage: Involves physically visiting stores like Target or Walgreens to hunt for discounted products.

  • Online arbitrage: You do all your sourcing from the comfort of your home using websites like Walmart.com, CVS.com, or BestBuy.com.



💡 How Does Online Arbitrage Work?

Here’s how a typical online arbitrage process goes:

  1. Find discounted or clearance items on online stores like Target.com or BigLots.com.

  2. Compare prices on Amazon to see if there’s a profitable margin.

  3. Buy the product if it meets your profit criteria.

  4. Receive the shipment, then either list the product for sale via FBM (Fulfilled by Merchant) or send it to Amazon’s warehouse via FBA (Fulfilled by Amazon).

  5. Collect your profits when it sells.



✅ Pros of Online Arbitrage

  1. Work from anywhere All you need is a device and Wi-Fi. Source inventory while watching Netflix or sipping coffee at home.

  2. Low upfront cost You don’t need to buy in bulk or manufacture products. Start with $50 or less and grow from there.

  3. Thousands of sourcing options With endless online stores, your product pool is much bigger than with local retail arbitrage.

  4. Free packaging Your online orders arrive with bubble wrap, boxes, and packing materials you can often reuse for Amazon FBA.

  5. Opportunity to scale Find a hot deal online? You can often buy larger quantities than what’s available in-store.



⚠️ Cons of Online Arbitrage

  1. Increased competition Since anyone, anywhere can shop online, you may run into more resellers sourcing the same deals.

  2. Time-consuming research Comparing prices, reading reviews, and checking fees across platforms can take time and focus.

  3. Profit calculation tools are less intuitive While tools exist, many require a paid subscription or manual entry for accurate profit analysis.



🧰 Tools to Help You Succeed in Online Arbitrage

You don’t need fancy software to begin, but the following free tools can boost your success rate:

  1. Amazon FBA Revenue Calculator Use this to estimate your actual profit after fees and shipping.

  2. Jungle Scout Sales Estimator Gives you monthly sales estimates based on Amazon sales rank and category.

  3. Brickseek.com Helps you find deals from big-box retailers and even compares pricing across platforms.

  4. Jungle Scout Chrome Extension (Paid) Offers deeper insight with sales history, pricing trends, competition levels, and profit margins.



🛍️ What Types of Products Should You Resell?

Here are the top 10 Amazon categories to explore:

  • Home & Kitchen

  • Beauty & Personal Care

  • Clothing, Shoes & Jewelry

  • Toys & Games

  • Health & Baby Care

  • Electronics

  • Sports & Outdoors

  • Pet Supplies

  • Baby Products

  • Office Supplies

These are highly searched and offer consistent demand—but don’t be afraid to explore niche markets too.



🔍 How to Analyze a Product: A Real Example

Let’s say you find a toy listed on Walmart.com for $5. On Amazon, the same product is going for $28.89. That’s a promising gap!

To verify the profit:

  • Find the ASIN on the Amazon product page.

  • Plug it into the FBA Revenue Calculator.

  • Enter your cost ($5) and selling price ($28.89).

  • Your estimated profit might be $12+ after Amazon fees.

Check demand using Jungle Scout’s Sales Estimator. If it sells 60+ units/month and has only two other sellers, you could likely sell 20 units a month!

Here’s a list of great places to start your product hunt:
