So Games Much Thrones Wow

I looked this shirt up online, and there was a link to Amazon. Did you know that you can buy this and some other Woot shirts on Amazon for $14.99, which includes Prime shipping? What??

A store called Increteeble is selling this design on shirts, mugs, etc. for a significant up-charge. Are they affiliated with Woot/Amazon? Or did they rip off the design to make a quick buck?
