About this tool

“Buy more, save more” deals as percentages

OfferActual discount per item
Buy 3, pay for 233.3%
Buy 4, pay for 325%
50% off the second item25% (when you buy both)
Get the second item free50% (when you buy both)
20% + 10% stacked28%

These deals are only worthwhile if you’d actually use the extra items. Buying twice as much to save 25% means spending 50% more than you planned.

Pay-in-full discounts, coupons, and shipping

  • Compare the final price, including shipping. A 10% discount on $150 ($15) won’t help if shipping costs $20 more than at another store.
  • A coupon applied to a sale price works like a stacked discount: the second percentage is taken off the already-reduced price.
  • Pay-in-full discount vs. interest-free installments: if the upfront discount is small, paying in installments and letting your money earn interest may be a better deal. Use the pay in full or installments calculator to compare.

False discount advertising

Advertising a “was” price that was never actually charged to make a discount look bigger may be considered deceptive advertising. Keep screenshots of prices from the days before a sale so you can compare them and, if needed, contact your local consumer protection agency.

Frequently asked questions

Is 20% + 10% the same as 30%?

No. Stacked discounts are applied one after another: 20% off followed by 10% off equals a total discount of 28%, not 30%.

How can I tell if a sale is genuine?

Compare the “was” price with the product’s price history. If the price went up before the sale, the actual discount is smaller—use the actual discount tab and enter the price you saw before.

How do I calculate the percentage discount I got?

Divide your savings by the original price, then multiply by 100. An item that costs $250 and sells for $199 is discounted by (51 ÷ 250) × 100 = 20.4%.

Is it really free? Is there a daily limit?

It's free with no daily limits. Processing happens on your device, so there's no per-use cost and no need to limit you.

Does it work on phones?

Yes. The site works in any modern browser on Android, iPhone, Windows, Mac, and Linux—no installation needed.
