I too am joining the "Eat from the Pantry Challenge" for the month of January. (Guess I had better stock up today, while I can, huh?) :)
I will allow myself the following: chicken, dairy, produce, FREE items, or items that cost under $1 (after cpns and sale). I will also purchase laundry, cleaning, and paper products as needed.
I am hoping to pocket the extra cash that I save towards our 2010 Disney vacation!
