here are the stores i have atm selling my designs
teepublic (largest number of designs atm): https://www.teepublic.com/user/dikleyt
redbubble (largest number of items to get designs on): https://www.redbubble.com/people/dikleyt

which one is cheapest varies depending on who is having sales, etc.
addendum: redbubble gives me the best margins, i've figured out
