Catch a leaked code by watching redemptions against expectations: a private code suddenly used far more than planned, by people outside its intended audience, is the classic sign it reached a public deal site. Spot the leak early to limit the damage, then retire, tighten, or replace the code.

Catch it early
A leaked code left running keeps draining margin. Catching the leak quickly, and acting on it, limits the damage, whereas discovering it weeks later means the discount has already been spent widely. Related: How Coupon Abuse Eats Your Margin
Respond to leaks
Once a leak is spotted, you can respond: retire the code, tighten its rules, or replace it. The important thing is that you know it happened, so a leak becomes a manageable event rather than a silent loss.
