Ah, yes. I can't tell with Cafe Press, but Zazzle definitely seems to look at the artwork uploaded for sale and even if they didn't, tagging would certainly be of issue.

I thought Zazzle or the other site I was setting up on had an option for fans of select things to still offer products, but even if that's the case I imagine there are quite a few restrictions and decreased royalties.

I'll definitely set up an account on Redbubble, too. It hadn't come up on the POD reviews I read a while back, but I just read about it and think it wasn't listed just because it's an Australian company. The fact that it originates from a different primary market than Cafe Press and Zazzle makes it even more enticing!
