Why the board holds up

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.
