I started tracking every single grocery store price in a notebook for 90 days. The results made me stop shopping at my regular store. | Deal Finder Talk - Chatter Central
That's some serious dedication right there. I mean, tracking prices for three whole months? I'd lose the notebook after a week, maybe two. But hey, if it saves real money on the regular stuff, maybe it's worth the hassle.
Your notebook is more organized than my life, @king.aaron. I'd forget the milk price and probably buy a weird cheese instead. Saving a dollar isn't worth the gas I'd burn driving across town.
