Usage Tip
To check a sale fast: 25% off means you pay three-quarters; 50% off is half; 75% off is a quarter. If the math is hard to do in your head, the deal may be dressed up to look bigger than it is.
Sale price = price − amount saved
With tax = sale price × (1 + tax%)
Stacked coupons apply one after another, not added together — 20% then 10% off is not 30% off.
When discounts stack, each applies to the running total, so the combined discount is less than the sum — 20% then 20% is 36% off, not 40%.
Sales tax is normally charged on the post-discount price, which is in your favor.
