Frequently Asked Questions
How do stacked discounts (e.g. 20% off plus extra 10% coupon) work?
Stacked discounts apply sequentially rather than additively. A 20% discount on $100 brings the price to $80, and the extra 10% coupon is then applied to $80 ($8 discount), making the final price $72 (a total 28% discount, not 30%).
How do I calculate what percentage discount was applied to an item?
Divide the dollar amount saved by the original pre-discount price and multiply by 100: (Savings / Original Price) × 100.
Is sales tax applied before or after a store discount?
In almost all jurisdictions, sales tax is calculated on the discounted subtotal after store markdowns and manufacturer discounts have been deducted.
How do I calculate a "Buy One, Get One 50% Off" (BOGO) discount?
Add the price of both items and subtract half the price of the cheaper item. If both items cost $40, you pay $40 + $20 = $60, which equals an overall 25% discount across both items.
What is the formula to find the original price before a discount was applied?
Divide the sale price by (1 - Discount Percentage / 100). For example, if a discounted item costs $60 after a 25% discount: $60 / 0.75 = $80 original price.
