I'm going to do this on my own terms. What I'm targeting, trying not to buy, is non-grocery food (food from gas stations, fast food, etc.). Also trying not to make any impulse purchases. I am, however, giving myself a few allowances. Next weekend (not sure which day) I will grocery shop as usual. And I am allowing myself to use gift cards - so, iced tea in the morning's still a go, and I have enough Subway points for one emergency six-inch sub if I need it.
