Flexify: Facebook Product Feed

I'm so positively surprised about how well this app works. We are using it to sync all our products from Shopify to our Pinterest profile which is now showing as a brand store. It works SO well and it even syncs our ratings and reviews to Pinterest. I love that this app is free for up until 1000 products which is an added bonus. Also the customer support was incredible. I had emailed them about how I can sync to Pinterest and Aby replied so quickly and made it so easy for me. Thank you so much!
