While your list is showing one store, Menu Planner 2 notices which aisles you check items off in first. After three trips to a store, if that isn’t the order of the store’s aisles, a card on your list and on the store’s screen offers to change it.
Review shows the store’s order (Now) beside How You Shop. Use This Order changes the store’s aisles; when you opened it from the store’s screen, save the store afterwards. Keep My Order leaves them alone, and the same order isn’t offered again.
A trip ends when you haven’t checked anything off for a few hours. Trips are remembered on the device you shop with, and only while the list is showing that one store.
