Tips for best results
A 50% off discount on a $200 item saves $100 — but a 30% off item that was originally $400 saves more ($120) even though the percentage looks smaller
Stack discounts carefully: 20% off and then another 10% off is not 30% off — it is 28% off because the second discount applies to the already-reduced price

Frequently asked questions
How do I calculate 20% off a price?
Multiply the price by 0.20 to get the discount amount, then subtract from the original price. Or multiply the original price by 0.80 to get the final price directly.
What if there are multiple discounts?
Apply them sequentially. First discount reduces the price, then the second discount is applied to the already-reduced price. The total effective discount is less than the sum of both percentages.
