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 Singapore checkout total
Confirm the discount, SGD total, GST or import treatment, delivery and return terms shown at checkout. Do not infer a threshold or payment option without a current source.
