Frequently asked questions
How is percent off calculated?
A 20%-off discount multiplies the original by 0.8, so you pay 80% and save 20%.
Can I handle buy-one-get-one deals?
Calculate each item's price and combine them; for bundle or threshold offers, divide the actual total paid by the original total to find the effective discount.
Are results rounded?
The sale price is shown to two decimals, matching how tills and stores price items.
