FeedHub: Google Shopping Feed

This app works fine for Facebook and Google data source feeds if you are directing customers to your Shopify for checkout, but DO NOT USE if you have Facebook/Instagram checkout enabled. It does not keep your inventory synced back to Shopify in realtime to prevent overselling on FB and IG. And IMO, for the price, it should. There are better apps (for less) when it comes to realtime sync, but none with the in depth filtering features. If you don't need advanced filters on the products you want synced, I would go with an app that updates products in realtime.
