Actually, yes you do. You maintain your shopping list between trips; whenever you need something, you put it on the list immediately. Then when you go shopping, you just take the list with you (if you're lucky, you don't need to move or copy it at all, you just get another reference to it). Once you're done, you empty the list - you now have a shopping list with zero items (until you get home and realize you forgot something).
