Test WooCommerce Coupon Combinations Before Advertising a Discount

Example: a banner that promises more than the rule

A banner says “20% off everything” while the coupon excludes an entire product category. The checkout may be following its settings correctly, but the customer journey remains misleading. Correct the campaign copy or eligibility rule; hiding the checkout warning does not resolve the mismatch.

Keep the offer maintainable

Record the coupon identifier, eligibility decisions and end date. Repeat the relevant cart cases after changing pricing or promotion extensions. Use clear rejection messages that explain an actionable condition. Avoid fake savings comparisons and confirm advertised prices with the person responsible for the store's pricing policy.

How many test baskets are enough?

Choose cases that exercise each meaningful eligibility boundary and combination. A small well-designed matrix can be more useful than many nearly identical purchases. Add a case whenever a new rule, exception or extension changes the logic, and retain expected totals for future regression checks.
