Hi there,
not sure if this is in response to my post or not, about special diet and price book, but my answer to the subject question is this:
Even if things are going up...dont' you want to be sure you know what and when you are paying for items? You have to buy them anyway! Don't you want to know the cheapest gas pumps in your town on a given day before you fill up?
I want to know the cheapest place, and time frame to buy toilet paper, or orange juice...know what i mean?
