need opinion on spreadshirt

Has anyone used spreadshirt? Im looking for a t-shirt affiliate that I can set up my own cart on my own webpage and basically build a brand. Im tired of the whole thin marketing approach. So that basically rules out zazzle.

Why do I want my own cart? I want to be able to put products in google and bing shopping. Not get banned from adwords esc. Want to build a legit site this time and not carry any products.

Thanks..
