We are still in the process to find a good candidate among webshops. We don’t have any funding, so the money transaction would be only between the t-shirt buyer and the web shop selling it. This webshop should provide the possibility either to sell the t-shirt with no revenue at all for us (HTC doesn’t hold any bank account) or to give revenues to a charity / no-profit organisation of our choice.
Another technical issue is that this design requires also the sleeves to be part of the printing process, while usually those webshops provide the printing only in the center square of the forepart of the t-shirt. If you have a candidate for a webshop with these requisites, please add it to the list in the wiki post.
