I ordered some t shirts through cafepress and the logos on them fell apart after being washed twice. Personally I would rather get better quality. I know my last BYC shirts have been washed many times and still look great!
While I would personally love to see a hoodie available, I also have to say it is a lot of money to tie up at one time for this forum.
I think a better idea would be:
1) Decide on a color and design.
2) See if there are enough members interested to preorder their hoodies.
Companies that do...
