I'm not taking sides on this issue but I can tell you that having T-Shirts mad with silkscreened multi color logos is not an inexpensive endeavor to undertake. Last time I looked you had to order assorted sizes and a large minimum quantity so, the up-front out of pocket cost can be prohibitive, especially if you are having them made on spec. It has been my experience in situations like this where everyone is hot to trot, that is until they have to actually pay for the idem, be it a T-Shirt, Dash Plaque, etc.
The Cigar City Flatheads made Dash plaques commemorating one of our events, with most of the proceeds going to a charity... We couldn't even get our out of pocket cash back so, we were hesitant to offer up the water transfer decals but, they sold out in just over a weeks time, so you never know what will or won't sell. You've got to be willing to take a chance and commit to spending money...
