A kitchen is rarely just the kitchen. There's the pantry down the hall, the bar cart, the second fridge in the garage. KitchenTalk keeps each one separately, and then puts them all on one board, side by side, so putting a shop away is a matter of ticking what belongs elsewhere and moving it once.
You don't have to go looking for that board. Scan the week's shop and it lands where you were standing, so KitchenTalk offers, right there under the receipt, to split it across your kitchens. Say later and the same offer waits in everyone's notifications, because a household should know a shop arrived.
