Discount Calculator
Work out final prices, stacked discounts (store + member + coupon), whether a spend-threshold coupon beats a percent-off, and the real discount behind 2nd-half-price or buy-N-get-M. Shows what you pay, what you save and the effective rate. Fully computed in your browser.
Discounts multiply in order, then the coupon is subtracted. Order can matter, so this follows the usual front-to-back convention.
A coupon applies once and only above the threshold; a percent-off scales. The larger the basket, the better percent-off usually is.
