So, I'm a total geek. I admit it. I love checking out my food costs, seeing how I can trim, and seeing how I'm doing. My hubby is a total Quicken geek. So, with about 15 mins of work I was able to pull up our food costs since 2000 (though 2000 numbers are estimated based on my memory. When I said "we spend WHAT?")
The all time low was just after I lost 57 lbs. We were eating out a LOT less, and we were both eating less food, period. The eating out bill crept up from there. A big difference from 2003 to 2004. As I got pregnant and gave birth, the eating out went up again. Until 2008, when it just became too much of a pain to eat out with a toddler.
