Personally, I look at the ads

keep track of what is in my freezer, and plan meals around sales/what I already have. I check out recipes and save them and sometimes look to them to buy food for them when I shop. And I do it by the week but I have been putting items on a calendar by the day so I remember to thaw stuff. This is a work in progress for me, being a working mother of four kids and with basically no eating out budget to speak of at this time.
On another note, we restarted the Dave Ramsey plan in October, and just paid off our first debt. Feels great to cross it off.
