Put your grocery list in once. See every item priced at each store, the lowest single-store basket, and what you save by splitting the trip.
Quantity can go first (2 milk), after an x (milk x2), or after a comma (milk, 2). No quantity means 1.
Click any cell in the table to enter a price by hand. To load many at once, download the template, fill in the price column, and import it. Your list and prices are saved in this browser only, so download a backup if you use more than one device.
