🤔

For "Was $100, now $80!" — is that really a deal? Use the calculate mode: 20% off. Compare to typical sale percentages in that category.

💡

For Black Friday and Prime Day, retailers sometimes inflate "original" prices to make discounts look bigger. Calculate against MSRP to verify.

🎯

For "limited time" offers, the calculated % off helps you decide if it's worth rushing or you can wait for a better sale.
