Sale price = original × (1 − discount%). Savings = original × discount%. For double discounts: apply sequentially, not additively (20% then 15% off is 32% total, not 35%). Verify whether the discount applies before or after sales tax—some jurisdictions tax the pre-discount price. 'BOGO' (buy-one-get-one) is effectively a 50% discount per item on two-item purchases.
