So, yep, I'm in the same boat. Ordered and paid for 2 T-shirts on 10 Sep 2015. Sent them emails. No reply. I kept the page open for the site and then when I refreshed the page tonight, the website was gone. I thought they may have just changed their domain, but no. A google search offered on the reviews on this site and a fb page which was clearly useless.
Coincidentally, I was suddenly getting emails from to other T-shirt companies offering similar designs at similar prices. Not going to trust any of them.
