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.

Telecom

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.
