Amazon to eBay arbitrage is one of the most straightforward dropshipping models: buy products on Amazon at one price, sell them on eBay at a higher price, and pocket the difference. The concept is simple, but finding genuinely profitable products requires a systematic approach.
In this guide, we'll show you exactly how to identify arbitrage opportunities, calculate your margins correctly, avoid common pitfalls, and scale your research process with the right tools.
How Amazon to eBay arbitrage works
The arbitrage model exploits price differences between Amazon and eBay for the same product. Here's the typical flow:
- Find a product on Amazon priced at £18
- Check eBay sold listings — the same product sells for £30
- List the product on eBay at £29.99
- When it sells, buy it from Amazon and ship it to your customer
- After eBay fees (£3.84) and payment processing (£1.17), you keep £6.98 profit
Why do products sell for more on eBay?
If this seems too good to be true, you're probably wondering: why would anyone pay more on eBay when they could just buy from Amazon? There are several reasons:
- Different buyer demographics: eBay attracts bargain hunters who don't always cross-check Amazon prices. Many buyers stick to one platform out of habit.
- Search behaviour: eBay buyers often search using different keywords than Amazon shoppers, leading to less price awareness.
- No Amazon Prime membership: Some buyers prefer eBay to avoid paying for Amazon Prime.
- Product presentation: Well-optimised eBay listings with better titles and images can justify slightly higher prices.
- Category preferences: Certain categories (collectibles, vintage items) are more popular on eBay, where buyers expect to pay market value rather than Amazon's discounted prices.
How to find profitable products
Finding arbitrage opportunities is part art, part science. Follow this process:
Step 1: Browse Amazon bestsellers and deals
Start with Amazon's Bestsellers, Hot New Releases, and Movers & Shakers pages in specific categories. These products have proven demand. Also check Amazon's daily deals and Lightning Deals for temporary price drops.
Step 2: Cross-check on eBay sold listings
For each potential product, search for it on eBay and filter by "Sold listings." This shows actual selling prices, not just what sellers are asking. Look for:
- At least 5-10 sales in the past 30 days (indicates demand)
- Consistent selling prices (not wildly fluctuating)
- Green prices dominating red ones (more sold than unsold)
💡 Tip: Focus on products priced between £15-£50. Lower prices have thin margins after fees. Higher prices have more risk (slower sales, higher return costs, more customer scrutiny).
Step 3: Calculate your true profit margin
This is where most beginners make mistakes. You must account for ALL fees and costs:
- Amazon purchase price: What you'll pay (including any delivery charges if not Prime-eligible)
- eBay final value fee: 12.8% of total sale price (including postage)
- Payment processing fee: PayPal or Managed Payments ~1.4%
- Returns provision: Budget 2-5% for returns/refunds
Step 4: Verify stock availability and delivery times
Check that the Amazon product is in stock and dispatched by Amazon. Third-party sellers on Amazon may have unreliable stock or slow shipping. For eBay, you want to guarantee dispatch within 3-4 working days.
Step 5: Check for VeRO restrictions
Before listing, search the brand name in eBay's VeRO database. Major brands like Apple, Nike, LEGO, and Disney actively protect their listings. Getting a VeRO takedown damages your seller metrics.
Calculating your profit margin
Let's walk through a real example to see how the numbers work:
Example: Wireless Bluetooth Speaker
| eBay selling price | £30.00 |
| Amazon purchase cost | -£18.00 |
| eBay final value fee (12.8%) | -£3.84 |
| Payment processing (1.4%) | -£0.42 |
| Returns provision (3%) | -£0.90 |
| Net profit | £6.84 (22.8%) |
A 22.8% margin is solid. Aim for at least 20% net profit after all costs. Remember: some products won't sell immediately, so your working capital will be tied up in unsold inventory.
Product categories that work well
Not all categories are equal for arbitrage. Here are the best performers:
Home & Garden
Kitchen gadgets, organisational tools, and decorative items. High turnover, decent margins, low return rates. Look for seasonal items (BBQ tools in summer, heaters in winter).
Electronics accessories
Phone cases, cables, chargers, Bluetooth speakers. Fast movers with consistent demand. Avoid flagship devices (too expensive, high return risk).
Health & Beauty
Skincare tools, grooming kits, fitness accessories. Evergreen demand. Watch out for expiry dates and authenticity concerns.
Pet supplies
Toys, grooming tools, feeding accessories. Pet owners are passionate buyers who don't always compare prices. Avoid food/treats (shelf life issues).
Office supplies
Desk organisers, stationery sets, ergonomic accessories. Steady demand from home workers. Low competition in niche sub-categories.
What to avoid
Certain product types cause more headaches than they're worth:
- Heavy or bulky items: Shipping costs eat into margins. A £5 profit disappears when Amazon charges £8 delivery because you're not Prime-eligible.
- Fragile items: Higher return rates and damage complaints. Glass, ceramics, and electronics with delicate screens are risky.
- Seasonal products: Christmas decorations sell well in November but sit unsold for 10 months. Your capital gets tied up.
- Heavily branded items: Nike, Apple, Sony, LEGO — all actively enforce VeRO. One takedown can damage your account.
- Products with many variations: Clothing (sizes, colours) leads to "item not as described" returns when customers order the wrong variant.
⚠️ Warning: Never list products from brands on eBay's VeRO list. Your account can be suspended immediately, and appeals are difficult. Check the VeRO database before listing any branded product.
Scaling with automation
Manual product research is feasible when you're managing 20-50 listings. Beyond that, you need automation to:
- Monitor Amazon prices: Prices change multiple times per day. Manual repricing is impossible at scale.
- Sync stock levels: Out-of-stock items on Amazon mean you can't fulfil eBay orders.
- Update eBay prices automatically: If Amazon raises their price, your eBay listing becomes unprofitable.
- Process orders faster: Manually copying addresses and placing Amazon orders takes 5-10 minutes per sale.
Tools like Coderom automate these tasks. The platform monitors Amazon prices every few hours, adjusts your eBay listings to maintain your target margin, and syncs stock availability. For high-volume sellers, the Chrome extension can even place Amazon orders automatically with a single click.
Key takeaways
- Amazon to eBay arbitrage works by exploiting price differences between platforms
- Focus on £15-£50 products with at least 20% net margin after all fees
- Use eBay sold listings to validate demand — look for consistent sales at stable prices
- Avoid VeRO brands, heavy items, and products with many variations
- Scale with automation once you exceed 50-100 products — manual management becomes unsustainable
Amazon to eBay arbitrage is one of the most accessible dropshipping models, but profitability depends on disciplined product selection and accurate margin calculations. Start with manual research to learn what works, then use automation to scale efficiently. With the right approach, you can build a sustainable arbitrage business with minimal upfront investment.
