CartSwap app — save on what you buy

How CartSwap works

Three taps between you and a smaller grocery bill.

1

Build your cart

Add items or scan barcodes while you shop at Walmart.

2

See cheaper swaps

CartSwap flags a comparable item at a lower price — same type of product, not a downgrade.

3

Save instantly

Apply the swaps and watch your total drop before checkout.

Real savings, real cart

Every trip has a little waste in it. CartSwap catches it.

In one cart, CartSwap flagged $6.99 in cheaper swaps — for example, Land O Lakes butter ($4.46) → Great Value ($3.06), saving $1.40 on the same thing. (Savings vary by cart.)
