OfferGuard demo video

Watch how OfferGuard detects repeat buyers at Shopify guest checkout and blocks discount abuse in real time.

What you'll see in this demo

This video walks through a real checkout scenario on a Shopify store protected by OfferGuard. A returning customer tries to reuse a new-customer discount by switching to a different email address and checking out as a guest.

You'll see how OfferGuard catches the attempt in under 50 milliseconds by cross-referencing five identity signals: normalized email, phone number, shipping address, IP address, and device fingerprint. The discount is automatically removed at checkout before the order is placed.

The demo also shows the merchant's view in the Shopify admin — every flagged checkout includes a detailed breakdown of which signals matched and why the discount was blocked.
