1 in 4 coupon codes fails at checkout. Across 78.8 million live checkout tests, 26.2% were rejected. That's one of the top findings from our new 2026 State of Coupon Codes report.

The viral conversation around Honey exposes a hidden incentive: most extensions are built to track your checkout, not save you money.
They get paid just for being the last click—even if the coupon code doesn't work.
Here's how we’re fixing this "Failure Economy" at SimplyCodes: simplycodes.com/blog/why-cou…
You think broken promo codes are just bad luck. They aren't.
The internet is economically engineered to waste your time at checkout.
We investigated the "Failure Economy" to understand why the current system rewards broken codes over working ones—and how we’re fixing it.
Here is what we found. 🧵👇
To solve this, we had to rethink the economics of truth.
We built a system based on Byzantine Fault Tolerance that rewards accuracy, not just clicks:
Double-blind human verification
Reputation staking (Accuracy = $)
Real-time consensus
We don't just sell codes; we sell certainty. 🧠
We are building the Determinism Layer for commerce.
In an age of AI and dynamic pricing, you need to know what is real.
