# Does the shared Shopify cart work if my Replo site is on replosites.com or another domain?

> Check which domains can share one cart between your Shopify theme and your Replo site.

A [shared cart](https://docs.replo.app/commerce/shopify-shared-cart.md) keeps one Shopify cart as shoppers move between your Shopify theme and your Replo site. Both sites read the cart from the same browser cookie.

No. Browsers only share cookies between a domain and its subdomains, so your Replo site must be on a subdomain of your store's primary domain.
