Why not offer shopping lists at the supermarket? Could be the first aisle. Ready-made shopping lists, two for $1.
You know… Call me crazy, but something like that could work? Ideally just free, but checklists for the 20 most common items to help remind you what you might miss, and also possibly recipes (frequently switched) from things the shop keeps in stock.








My bios/similar are either empty or whatever I put there as a teen… Except for one where I put “Green Is My Pepper”, I should use that more.
