How to stop Amazon and eBay resellers from buying your products on Shopify
A reseller ring is one person, or a small group, placing many orders on your store under different names, emails and cards to get around purchase limits, then reselling the stock on Amazon, eBay or other marketplaces at a markup or below your price. The giveaway is the address: many different identities shipping to the same house, warehouse or prep center.
Warning signs
- Several different customer names or emails shipping to one street address within weeks
- Multiple orders to the same address in a few days, often just under your per-order limit
- Your products showing up on Amazon or eBay soon after a drop or a sale
- New accounts buying only your limited or best-selling items at full quantity
- Different cards used on orders that all go to one place
How to prevent it on Shopify
Things any merchant can do, with or without an app.
- Set a per-customer quantity limit on limited products, knowing it only stops one account at a time
- Search Amazon and eBay for your products after launches, and note the seller names and shipping locations
- Check your Orders list by shipping address before launching a drop
- Tag known reseller addresses and hold their orders before fulfillment
- Cancel and refund confirmed reseller orders before they ship, not after

Questions
Can Shopify stop resellers on its own?
Shopify can limit quantities per order, but resellers get around that with several accounts. Catching them means looking across orders at shared addresses, names, emails and cards, which is what a screening app like Interceptor does.
How do I find out who is reselling my products on Amazon or eBay?
Search the marketplaces for your products and note seller names and where they ship from. Then look in your own orders for addresses with many different customers. Those addresses are usually the reseller's.
Will I block real customers who share an address?
Interceptor only flags and holds. You see why an order was flagged and release it with one click if it's a household or office.
