Printify: Print on Demand

I am just getting started with print on demand. I like that Printify makes the process of creating and publishing products very user friendly. Also, I've done some comparison shopping, and I feel that Printify offers the most bang for your buck. So far their product integration with Shopify has been seamless. The only reason I'm not giving 5 stars is that I think they could do better with the mock-ups. Right now the mock-up choices are limited, and seem to be based on the specific product. I don't expect them to have mock-ups like you would get with Placeit, but I think they could at least do as good as Printful does with their mock-up choices,
