I have been married for ten years. When my wife and I first started grocery shopping, we spent about $100 every two weeks to get what we needed. We're probably like most people, we pretty much buy the same thing every two weeks. Ten years later, we're still buy the same thing and spending about $325 every two weeks for the same family of three. I'm not really a big math guy, but it seems to me that $325 is more than $100 and if that is not inflation, I don't know what is.
