Keep a running total while you shop. Just enter each item's price as you add it to your cart. The calculator automatically sums everything so you know exactly what you'll spend before you reach checkout.
Grocery prices add up fast. A quick trip for "a few things" can easily hit $50 or $100 before you know it. Tracking your running total helps you stay on budget, make trade-offs in the moment, and avoid checkout surprises.
If the whole household adds to the grocery list during the week, build it as a free shared grocery list first - everyone edits the same list from their own phone, no accounts. Then bring it here and add prices as you shop.
