Simprosys Google Shopping Feed

We had been using the Shopify Google Shopping free app for the last 2 years but its technical support can't simply deal with any issues with their own app or the ones related to Merchant Center. On the contrary, Feed for Google Shopping app and their technical support team proved to be knowledgeable, responsive and highly professional, guiding and helping us not only with the initial set up, which was a complex process for us, but also solving some of the issues we had in Google Merchant Center. If you are serious about running shopping ad campaigns, this app is the solution you need.
