Printful: Print on Demand

Tried shirts.io first and had a series of frustrating experiences with them, then I discovered Printful and switched. Best...decision...ever. It truly is fully automated and once it's set up, I don't have to do anything. This is already saving me tons of time and allowing me to increase the number of products I can offer in my store since I no longer have to purchase inventory up front. My only complaint is no discounts for bulk order of the same style/color/design. But for just-in-time production of single items, this is by far the best solution.
