Simprosys Google Shopping Feed

Fantastic App. This app directly syncs your Shopify Catalog (products) to the GMC without the hassle of using pesky excel sheets. All updates made on your product pages can quickly sync up with the GMC. It also has multi-country level support. My main shop is in the US, and I used my same GMC to create a separate feed for the EU and advertise there!
Also I had an issue with some products not syncing from the US and EU at the same time but they quickly resolved it. Great and must-have app for anyone advertising products on Google!
