Find your zombie codes before Black Friday does.
Old promo codes don't die. They get posted on coupon sites, picked up by coupon extensions, and keep working for years. Enter your store. We test every publicly posted code in your own checkout and show the deepest discount a stranger can get today.
Free. Shopify stores only. No install and no login. We never place an order.
How the scan works
01
We collect the codes posted for your store
From public coupon listings anyone can read. We don't guess codes and we don't log in anywhere.
02
We try each one in your own cart
Your cart tells us whether a code is accepted and exactly how much it takes off. Coupon sites are often wrong about both.
03
We look for the worst case
Codes on top of sale prices. Codes combined with each other. Fixed-dollar codes on your cheapest product.
Why this week
If your Black Friday sale is a price markdown, every code that still works comes off the marked-down price. If it is an automatic discount, codes combine with it whenever the combination box is ticked. Shoppers with a coupon extension don't have to find the code. It is applied for them.
Questions
- Is this safe to run on my store?
- Yes. We create a few dozen test carts through Shopify's public storefront API, the same one your theme uses. No checkout is started and no order is placed.
- Why are the codes masked?
- So nobody can use this page as a coupon finder for your store. The unmasked list goes only to an email address at the store's own domain.
- Some of these codes are supposed to work. Is that a problem?
- Maybe not today. The scan shows what a stranger can get, and you decide what is intended. What changes on Black Friday is that the same codes come off your sale prices.
- It says my store isn't supported.
- The scan works on Shopify stores whose public storefront API is reachable. Password-protected stores and some custom storefronts are not.
