Frequently Asked Questions

How do you calculate 20% off in your head?

A simple mental shortcut: move the decimal point one place to the left to find 10% of the price, then double that number to find 20%. For example, on a $60 item, 10% is $6, so 20% off is $12 (final price $48).

How do stacked discounts (like 20% off plus an extra 10% off) work?

Stacked discounts are sequential, not additive. A 20% discount on $100 drops the price to $80. The additional 10% discount applies to $80 (saving $8), resulting in a final price of $72 (a total discount of 28%, not 30%).
