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.
