Amazon to eBay Arbitrage: Complete Step-by-Step Guide

What is Amazon to eBay Arbitrage?

Amazon to eBay arbitrage means finding products on Amazon that are priced lower than what people pay for them on eBay. You list the product on eBay at a higher price. When someone buys it, you purchase it from Amazon and ship it directly to your eBay buyer.

The difference between the eBay selling price and the Amazon purchase price (minus fees) is your profit.

Why Does This Work?

Different audiences. Millions of eBay buyers never check Amazon. They search eBay first, find your listing, and buy it. They are happy with the product, you are happy with the profit.

Price differences exist everywhere. Amazon runs deals, clearance sales, and Prime-exclusive pricing that creates price gaps between platforms. These gaps are your opportunity.

Prime delivery advantage. When you buy from Amazon with Prime, your eBay buyer gets fast delivery (1-2 days in the UK, 2-3 days in the US). This means great feedback and repeat customers.

Step 1: Set Up Your Accounts

You need an eBay seller account (business account recommended for higher limits) and an Amazon Prime account (for free fast shipping). If you are outside the US, use the Amazon marketplace in your country — Amazon UK, Amazon DE, Amazon AU all work.

Step 2: Find Profitable Products

This is the most important step. You need to find products where the eBay selling price is higher than the Amazon price plus eBay fees (approximately 13%) plus your desired profit margin.

Manual Method

Browse Amazon categories, find interesting products, search eBay for the same product, compare prices. This works but is extremely slow — expect 2-3 profitable products per hour.

Automated Method with UnicornDS

Use the Product Hunter feature in UnicornDS. Enter keywords, and it searches Amazon, sorts products by reviews (proven sellers), checks VERO compliance, and shows you the price data. You can find 20-50 profitable products per hour instead of 2-3.

The Competitor Scanner is even faster — enter a successful eBay seller's username, and UnicornDS shows you everything they sell. If they are making money on it, you can too.

Step 3: Check Before You List

Before listing any product, verify three things:

VERO check: Is the brand restricted on eBay? If yes, do not list it. UnicornDS checks this automatically against 3,629 brands.

Stock check: Is the product actually in stock on Amazon? Nothing ruins your eBay metrics faster than cancelled orders. UnicornDS's Stock Checker verifies availability, quantity, seller, and Prime status.

Profit calculation: After eBay fees (approximately 13%), PayPal or managed payments fees, and the Amazon price, is there still profit? A good rule is minimum 15-20% margin after all fees.

Step 4: Create Your eBay Listing

A good eBay listing needs an optimised title (80 characters, keyword-rich), clear product images, accurate item specifics, and competitive pricing.

With UnicornDS, one click creates the listing from the Amazon product page. The AI Title Builder generates an SEO-optimised eBay title, images are pulled automatically, and pricing is calculated with your markup percentage.

For high volume, the Bulk Lister lets you list 50-100 products at once with concurrent processing.

Step 5: Fulfil Orders

When someone buys your product on eBay, you go to Amazon, purchase the product, and enter your eBay buyer's delivery address as the shipping address. Amazon ships it directly to them. You never touch the product.

Important: Do not include an Amazon receipt or gift receipt in the shipment. Amazon has options to exclude pricing information during checkout.

Step 6: Scale Up

Once you have your first 10-20 profitable listings, it is time to scale. The more listings you have, the more sales you make. Successful arbitrage sellers typically run 500-3,000 active listings.

Use the Competitor Scanner to continuously find new products. Monitor your listings with the Tracker. Send offers to watchers to convert them into sales.

How Much Can You Make?

Typical Amazon to eBay arbitrage margins range from 15-40% profit per item. With 500 active listings, you might sell 5-15 items per day at an average profit of £5-15 per item. That is £25-225 per day, or £750-£6,750 per month.

Top sellers with 2,000-3,000 listings report monthly revenues exceeding £20,000 with net profits of £3,000-£8,000.

Common Mistakes to Avoid

Listing VERO brands: This will get your account suspended. Always check first.

Not checking stock: Cancelled orders destroy your eBay seller metrics and can lead to account restrictions.

Pricing too low: Remember to account for eBay fees (13%), payment processing, returns, and your time. A 10% margin sounds good but disappears after fees.

Not diversifying: Do not rely on one product or category. Spread across many products to reduce risk.
