Vistaprint is where I make my business cards and other business related stuff...they're always marking stuff down cheap, or if you wait...it'll be free down the road a week or so.
I just made up two anti-BSL shirts with Score's pics...that cost me under $10 ($4.99 for uploading pic and $4.10 for shipping) each, the tee shirt itself was free. They are only white (or gray for a small fee)...but hold up well (I ordered some for my business a while back). You can put a couple of lines of text on them, and use different fonts and colors.
Just thought I'd pass it on. We went to our first Anti-BSL rally, and I felt naked without anything with Score's pic on it.... Now I'm set for the next one!
