I've started taking notes at my local grocery store of prices on certain items I know I'll buy often. I was pleasantly suprised to find 6 lb. cans of tomato sauce and diced tomatoes; even Sam's didn't have them last time I looked. Now I am totally without excuses to avoid making my gigantic batch of pasta sauce.
I've also started an inventory of pantry items. Since there's stuff scattered all around the kitchen and down into the basement storage room, this could take awhile! But, I'm borrowing the 15-minute idea from The FlyLady, and doing a little at a time. I also want to run out to the van and find the grocery receipt I tossed on dash. I want to keep every one for the next couple of weeks to track spending habits. That way I can show the kids why they don't need to tag along everytime I go to the store!
