Coupon Assistant (ad-free)

The Coupon Assistant helps the shopper choose between different size packages of the same item by calculating the per-unit price of both packages (with or without a fixed-value coupon) and indicating which is less expensive.

Have you ever found yourself stymied at the store, trying to choose between a smaller, less expensive package and a larger package with a lower per-unit cost? With a fixed-value coupon, sometimes that choice gets flipped on its head and the after-coupon price per unit ends up lower for the smaller package.
