On a standard sheet of paper I wrote out a list of all the grocery items that we buy. The list has several columns on it and it is in the order the items are found in the store. Using our printer, I print the list on both sides of the paper, (it is good for 2 shopping trips).
Everyone in the family uses a highlighter to highlight the items that I need to buy. Before my weekly shopping trip I review the list and highlight what we need. At the end of the list is an "Other" spot for those items that are not on the list, (furnace filters, prescriptions, and other seldom bought items).
My list saves a lot of time in the store and items are not forgotten.
