Put the price for any item in the appropriate box and hit Enter to compute the prices for the other quantities and container sizes.

Simple math can be entered in the box as well. For instance, to figure the cost when something is advertised at 4 for $9.50, input 9.50/4 and then Enter.

There is a liquid volume calculator for a couple of common beverage sizes after the price calculator.

When this was made, a "12-pack" was always a pack of twelve 12 oz. cans or bottles. That's how all the computations work.
