Have you seen those programs for sale that map out your favorite grocery store, aisle by aisle, to make a customized grocery list? I haven't purchased one, but I thought, "Why not make my own?".
So, I went to the grocery store with pen and paper in hand. As I did my shopping, I jotted down the main items on each aisle. I used those overhead aisle markers for reference and also included things I usually buy that were not on the signs.
Later, at home, I used a spreadsheet to make my master grocer list. I put everything in order, by aisle, and tried to include anything I would ever buy.
When it's time to make a grocery list, I print it out and circle the things I need. If I need something that isn't on the list, I pencil it in, and when I'm at the store I take note which aisle it's on. Then, I add it to my spreadsheet in the appropriate spot and save my changes.
