Why the board holds up
The floor rules
Ranked by live signals
Codes rise and fall on real member usage and votes; nothing is pinned.
Vote after you try
Thumbs feed the success rate shown on every code.
No fake urgency
No countdowns, no invented stock warnings; when a code stops working it drops.
About the store

Playbook
Run these plays
Start at the top — The #1 code carries the strongest recent signal.
Codes vs deals — A peel hides a code to paste at checkout; GET DEAL links go straight to the offer, no code needed.
If a code fails — Vote it down and try the next; the board reorders on what actually works.
Straight answers
What does the success rate mean?
It reflects recent member feedback on that code — thumbs up and down left after checkout.
What happens when a code stops working?
It drops off the board. Nothing is kept around once it stops working for members.
Do I need an account to use a code?
No. Reveal any code and copy it — no sign-up required.
