Read each coupon's current terms, identify eligible products and minimum spend, then test codes in the basket before paying. Watch the order in which percentage and fixed discounts apply, plus exclusions for sale goods, memberships, shipping or gift cards. Treat a code as savings only when checkout accepts it.

Stacking
Two benefits applying to the same transaction under their terms
Threshold
Check whether it is measured before or after other discounts
Proof
The accepted order summary, not an unverified coupon page
1
Open the retailer's own promotion terms and record expiry, market, channel and customer eligibility.
2
Check excluded brands, categories, sale items, subscriptions, gift cards, delivery and taxes.
3
Test one code at a time, then together, and note the order of calculation.
4
Compare the accepted final basket with the best no-code alternative before paying.
Translate the terms into a checklist
Coupon terms often answer five separate questions: who qualifies, what qualifies, where it works, when it works and whether another promotion may be combined. Check country, account status, first-order restrictions, app-only requirements, product exclusions and minimum spend.
The calculation order matters. A fixed-value code applied before a percentage code can produce a different total from the reverse. A minimum-spend threshold may be tested before or after another discount. Do not infer the order; use the basket and keep the final summary.
Test without distorting the basket
Adding an unwanted item merely to cross a threshold is spending, not saving. Compare the accepted basket total with the best alternative basket that meets your actual need. Include delivery changes: a coupon can reduce the merchandise total below a free-shipping threshold.
Treat unsolicited codes as a security risk
Unexpected “exclusive coupon” messages can lead to imitation login pages or malware. Do not sign in through the message. Navigate to the retailer through a bookmark or independently typed address, and never provide payment credentials merely to reveal a code.
