Buyer beware. I'm removing the link to the Zazzle shirts I created because I received my shirts and the quality is really sub-standard. You can get much better results from a real tshirt screen-printing service. No idea if Cafe Press will be any better.

Judging from this discussion of Zazzle on Dealtime, other people have had the same bad experiences. The biggest problem I have with these folks is that you cannot delete products from their site and they will continue to run your shirt perpetually. I didn't read the agreement, but according to others who have uploaded art work on Zazzle, there is no way to remove their art work, and Zazzle can continue to profit from your work even if you no longer want to sell through them. That may be good business for them, but it's really bad for the creators of the art work.

So my opinion is to stay away from Zazzle for dark t-shirts and wait to see how Cafe Press does with theirs. I'm having a really hard time imagining that the quality would be any good for any of these types of shirt printing services on black.

UPDATE: Black TShirts on Cafe Press are now up for sale!
