My wife came home from the hair salon with a bottle of shampoo. I looked at the price tag and said, "You paid that much for this? Do you know what that stuff costs per gallon?" She replied calmly, "But I didnt buy a gallon. I only bought this little bottle, and besides, do you know what that Scotch you drink costs per gallon?" I had to admit that I didnt know. So I wrote this little app to tell me. And to tell you.
For liquids only, this app will tell you the cost per gallon and per ounce of any liquid that you buy. Simply enter the price and size and there you have it. You can save your items to a list which you can then export to Numbers or Excel.
