You can check out the t-shirts that are available at:
A couple of words:
1. I have ordered one and have not received it yet, so I am uncertain of how good the quality is. If you want to wait, I can let you know what I think of it when I receive it. I can't make any guarantees of the quality, until I see it.
2. We did not mark the price up at all and don't receive any funds from the sale.
3. We will be working on the stickers as well. I'm not sure whether to do the stickers though cafepress.com or stickerrobot.com. I will let you know when those are ready.
Let me know what you guys think.
Hope all is well.
