LitCommerce eBay Etsy Amazon +

This app works as intended. I was able to push all of my Etsy products to my Shopify store and it was very easy. Much easier than some other methods I have tried in the past. Customer Support is also awesome and helped me immediately with the couple of questions I did have. At this point I would recommend LitCommerce if you want to integrate Etsy and Shopify. I haven't explored other sales channels yet.
