See every featureShoppers browse on a phone and buy on a laptop. Cart Relay saves a signed-in customer's cart against their customer account and puts it back when they sign in on another device. No link to click, no code to enter. If the second device already has a cart, the two are combined: quantities of shared items add up and no line is dropped.

Customers login once on each device to keep their shopping progress updated in the background. Our app preserves cart items even if a user logs out, restoring them when user visits on same device again.
