Printful: Print on Demand

I've been using Printful service for about a year now. I have used/using other services also however, Printful is one of the better POD services out there. The app is great relative to other apps in the same market, although it can improve. The quality of the print job is fantastic, and the turn-around meets my expectations. I consider myself a novice at this point, and I am sure there are a whole bunch of things I have not tried yet.
