I just found this again

http://www.cafepress.com/aliencc

This was United-TI store until around 2009 or so when they removed their ads, but I didn't know it was still actually open. I wonder if it still works since Cafepress produces the items for you when purchasing stuff, but the Paypal account tied to the store may not necessarily work anymore?

Regardless, this is some quite vintage TI stuff. It would be fun to see if other calc sites used Cafepress in the past to see if their stuff is still for sale.
