Stack a store discount, coupons, marketplace tiers and a subsidy to see what the buyer pays and the seller keeps
Share of the list price the buyer pays — 85 means 15% off
The order matches checkout: store discount → shop coupon → marketplace tiers → subsidy. A tier threshold is checked against the amount before it applies, and with repeat on, every full threshold counts. The platform funds the subsidy, so it is added back to what the seller receives. Real rules differ by category and campaign (exclusions, cross-store baskets, coupon returns), so treat this as the floor price.
