🧮 满减 Coupon Stacker
How threshold coupons work
满减 (mǎn jiǎn) means "full-reduce": for every ¥300 you spend, you save ¥50. Platforms usually apply store discounts first, then threshold coupons, then flat coupons. Rules vary, so always check the checkout preview.
- Add a small filler item to cross the next threshold only if you'd buy it anyway.
- Split large carts into separate orders when thresholds don't stack.
- Add card or portal cashback on top.

Paying in yuan?
Many cards add a 2–3% foreign-transaction fee. A no-FX-fee card, or paying in the platform's local-currency checkout, can wipe out that cost. Compare the platform's converted price with the mid-market rate shown here.
