I've started getting more orders, and at a point where using purely POD is losing me potential profit. But the problem is I'm not from the US where my main customer group is, so I can't hold and ship my inventory myself.
Are there any POD providers like Printful that offer to keep inventory in addition to printing and fulfillment? Something like FBA, but universal? Printing products in bulk would save a lot of money since I know now which ones sell.
