My wife has been made aware that she must write exactly what she wants on the shopping list (I do the shopping); I get what is on the list. If what she wrote is incorrect, so too will be what I buy. If there's ambiguity, I call her. I find food shopping to be very high stress (because half the things I buy involve me asking myself if it's the right thing, what I might be reading incorrectly, etc). If the shopping list is particularly odd (she's trying a new recipe and needs lots of unusual, specific ingredients), I make her do that trip.
