Do you price per ounce or the actual price?

I try to buy whatever has the best price per ounce, as long as the total price fits into my budget. I don't mind cutting or shredding myself to save a few cents, and I don't mind having a bit extra to freeze or put away for later. As long as I can afford the package, I'll buy the best bargin.

I almost always look at the price per ounce and try to buy whatever's the better deal, even if it's something I may not be able to use before the expiration date, I may be able to refrigerate or freeze it and use it later.

Before they started posting the price per ounce in the supermarkets, I still calculated it myself in order to make an informed choice of which product to buy. My pocket computer has a calculator and also a history of what price I've paid at various stores for various items, so I use it pretty fanatically to get the best deals. I also look at the order the ingredients are listed in on the labels too, because a jar of something that has water as the first ingredient might weigh more ounces, but the ounces might not be food. It is hard to beat dollar stores for some food items! Yes, like you, I am thrifty when buying.

It depends on what I've got to spend and how much I actually need, you know? Since a lot of things I buy I only need in small quantities because I won't use it all before it expires/goes stale I probably buy more by the lower package price than by lower per ounce price.
