How to save at the supermarket — 5 simple tips

The price of an identical product can differ by tens of percent between chains — and even between branches of the same chain. A quick comparison before you shop is the simplest way to save.

Tip 1 — compare by barcode. The same barcode is the exact same product, so the comparison is fair. Search by name or barcode and see the cheapest price at every chain.

Tip 2 — check by your city. The cheapest price depends on the branches near you. Pick your city or share your location to see relevant prices.

Tip 3 — follow the deals. Chains publish daily promotions; the deals page gathers the real discounts in one place.

Tip 4 — plan a list. Buying in one chain usually beats random hopping. Tip 5 — do not assume the "cheap" chain is always cheapest: it changes product by product.
