I am a Independent Rep With LogoWear Dircet and what they advertise is legit,they are for real.
You can also try Cafe Press and Zazzle. Those sites are free to join. As long as you have your own designs (they don't have to be fancy), you can add them to shirts, caps, bags hoodies, etc.
If someone buys from your store, then Cafe Press or Zazzle will do the printing and the delivering. That way you don't have to hold on to any of the inventory unless you want to.
