My grocery shopping list has:
An alphabetic list of all items in the list with a check box
After I check an item it is moved to a "Need List"
When I go grocery shopping I refer to the "Need list"
As I put items in my shopping card I check items in the need list
They are then removed from the "need list" and placed in the "Done List"
