When a promo code fails
Confirm market, currency, customer type, app or web channel, minimum spend, discount cap, product status, payment method and stacking restrictions.
SHOPPING GUIDES
Turn an offer into a real saving
Good shopping decisions also consider eligibility, landed cost, return cost and alternatives when a code fails.
Compare landed cost
Subtract only confirmed discounts, then include delivery, tax, duty, payment and currency-conversion costs.
Estimate a refund
Start from the amount paid and identify delivery charges, return fees, duty and other amounts that may not be refundable.
Judge evidence quality
Treat missing sources, dates, eligibility conditions and sample sizes as uncertainty rather than proof.
Check the full UK basket total
Confirm the discount, delivery charge, tax or duty treatment and return terms shown for the UK basket. A discount code from another market is not evidence that it will work in the UK.
