Read the deal
What you will actually pay and exactly how much stays in your pocket.
Discount questions, answered
Is my data sent to a server?
No. It is instant local arithmetic; nothing about what you are buying or paying leaves your browser.
How do stacked discounts work?
An extra 20% off an already 30%-off price is NOT 50% off - run the tool twice: 100 → 70, then 70 → 56, an effective 44% off. Retailers count on people not doing this math.
How do I reverse it - find the original price?
Divide the sale price by (1 − discount): something at 60 after 25% off was 80. Running the numbers here makes store labels easy to sanity-check.
