And we're live.
http://www.cafepress.com/theflatearthsocietyNote: This store is managed almost entirely by CafePress. I uploaded the designs, but ultimately, I have no control over the quality of the print and t-shirts. I've had some past experiences with them and they were pretty good, but I cannot take any responsibility etc. etc.
I set all markups to $0, so the prices are exactly what CafePress demands. I get nothing out of this.
I've ordered one of the t-shirts myself to get a general idea of how they turn out. I'll write a short review when I've received it (January 12th-13th, according to the order summary). If you're on the fence or would like some reassurance from a real human rather than a machine, you may want to wait for that.
CafePress has a 30-day return policy. I've placed a link to customer support prominently on the page. I won't be able to provide any support for the purchases made through CafePress, so please contact them directly.
For the time being, I am not announcing this store on Facebook or elsewhere. I'd like to see my t-shirt before I do so, just to be on the safe side. That said, like I said, I've used a bunch of CafePress stores before and I never had any qualms about the quality of their products.
Credit goes to Blanko for virtually everything artistic: the designs of the shirts, the logo, the design of the page. You know the drill.
