Frequently asked questions

Is tax applied before or after the discount?

Tax is applied after the discount, on the sale price. That is how it works in most US states and most online carts.

Can I stack two discounts?

Yes - run the first discount, then use that result as the price for a second calculation to compare the combined effect.

Does it work for "buy 2 get 1 free"?

Not directly. For that deal, the effective discount is 1/3 off the total, so enter about 33.33% to see the equivalent single-item price.
