How sale prices work
A discount is a percentage taken off the original price. 30% off $80 means you pay 70% of $80, which is $56, saving $24. “Stacked” discounts — like “take a further 10% off already-reduced stock” — apply to the already-discounted price, not the original, so they’re worth less than simply adding the percentages together. This tool handles both, and shows your real total saving as a percentage so you can compare offers honestly.
