Understand the discount
Coupon & discount comparator
Compare two offers using what you will actually pay—not the size of the percentage or the headline coupon value. Combine one sale price and one coupon per offer without building a confusing stacking scenario.
Coupon & discount comparator
Compare two final prices
Use the price you would normally pay, add an optional sale price, then apply one coupon. Dollar-off coupons apply once to the offer total.
Enter the regular price for both offers to see which costs less after discounts.
How to enter an offer
Use the regular price for one package. If the product is already on sale, add the sale price. Then choose either percentage off or dollar amount off. “Packages purchased” handles a requirement such as buying two, while “Items in each package” turns the final total into an effective price per item.
A dollar-off coupon is deducted once from the whole offer. A percentage coupon is applied to the sale total. Discounts stop at zero; the tool does not model rebates, loyalty points, tax, coupon order, or store-specific stacking rules.
Compare the same purchase
The winning offer is the lower final checkout total. If quantities differ, also inspect the effective price per item. A lower total for fewer items and a lower per-item cost answer different questions.
For packages measured in ounces, liters, or another amount, use Compare Deals after calculating each final price. See the methodology for formulas and a worked percentage-versus-dollar example. For a simple restaurant total, use the Tip Calculator.
