Rules are the guardrails

A discount's rules, who can use it, how often, in what combination, are the guardrails that keep a promotion doing what you intended. Loose rules are exactly where abuse gets in.

Anticipate the loopholes

Most abuse exploits a rule you did not think to set. Considering how a code could be misused, before you launch it, lets you close the obvious loopholes in advance rather than after they are exploited.

Keep them enforceable

A rule that is not enforced is just a suggestion. Rules only protect you if they are actually applied at checkout, so the discount genuinely behaves the way you designed it to.

Balance protection and friction

Rules that are too tight frustrate honest customers; too loose invite abuse. The art is setting rules that stop the abuse you actually see while keeping the promotion easy for genuine buyers to use.
