Firecart: Persistent Cart Sync

Easy plug-and-play app for cart persistence across devices and sessions. Their in-app customer support is excellent! Junaid helped find and fix an ongoing issue with our site in a matter of hours, where it took Shopify support many weeks to even find. Highly recommend this app!

There's no installation process. You simply install it, that's all. Even if you add it to your cart as a guest, it stays saved in your browser. When you log in with your account, the cart in your account remains saved, and you can view it on mobile devices, too. Easy, even for a monkey. GO TRY.

I would leave a 5 star but I blindly installed this app, because everything else was trying to do too much. The reason for the 4 star is because I haven't had enough time to test and see how it integrates with my theme. However it does exactly as advertised, and allowed me to sync my customers carts across sessions.
