Works great, super simple to set up, and love the automation you can turn on and it'll work in the background.

Support is helpful and walks you through everything. The app is a bit complicated to set up. You cannot use this on a Facebook page that already has a Shop setup connected to Shopify, so you'll have to create a new FB page for this. I'm waiting for my marketplace application to be approved for now.

Super easy to use, I'm very happy with it! Love Printful and I'm happy to be able to use it with Shopify!
