Jumping on the bandwagon, only 3 or so years too late; Your humble narrator's blog now has its first pieces of CafePress merchandise, offering a positive, life-affirming philosophy in the classic old-skool Macintosh user-interface idiom. I got mine in the mail a few days ago, and was impressed with how well the printing came out. (I had been a bit skeptical about the quality of those print-to-order places, but CafePress's quality seems top-notch.) I wore it to the blogmeet tonight.
Anyway, why pay $120 for a Japanese-robot-glyph/ironic-retro-porn T-shirt on Chapel St. when you can have one of these for only US$15 (plus exorbitant shipping from the other side of the world, of course)? Or something like that.
