How to Make One Grocery List for Every Store You Shop At

Shop at Costco, Trader Joe’s and a regular supermarket? Write one list and let each item land under the store you buy it at.

The problem with one list for several stores

Lots of households split their shopping: bulk basics at Costco, snacks and frozen food at Trader Joe’s, everything else at the supermarket down the road. A single list doesn’t fit that. You end up scanning the whole thing in every store, or keeping three lists that drift out of sync.

The fix is to keep one list, but let every item know which store it belongs to.

Decide where each item usually comes from

You already know most of this. Go through your regulars and give each one a home store:

  • Bulk and paper goods: often the warehouse club
  • Specialty items: the store that has the brand you like
  • Fresh produce and quick top ups: whichever store is closest

Not sure which store is cheapest for an item? Your receipts can tell you. Here’s how to compare.

Write once, sort by store

During the week, add things to one list as you think of them. Before you shop, group the list by store. Now each stop has its own short list, and nothing gets forgotten because it was written under the wrong store.

Plan the route

With the list split, you can see whether a store is worth the trip this week. If only two items are under one store, they might wait until next time, or move to a store you’re already visiting. For more on when a second store pays off, see shopping at more than one store.

How AisleSplit does it

In AisleSplit you type your whole week into one list, and each item is routed to a store automatically: the store you starred for it, or the store your receipts show you buy it at most. You can move any item with a tap, and within each store the list is in aisle order. More on aisle order.

Your list also works in the store with no signal, and check offs sync when you’re back online.
