I grew up watching my mother shop for the family from a handwritten grocery list that she had mimeographed (remember those smelly blue things?). When I was out on my own, I created one on the computer even long before the babies started coming.
The list is organized according to how we shop the store. I have a list that has Aldi and Wal-Mart on one page, as well as one for Wal-Mart only. (We shopped Wal-Mart only last weekend from 10pm-12am. It was the only free time we had!)
Since it has the items that we use most, I just circle what I need and note quantities. There are also blank spots to write in more unusual needs. I've formatted it so that I can rip it down the middle so Bryan and I can "divide and conquer."
