So, I recently got onto this website specifically for fanbases called Teepublic. It looks pretty cool to me. As a seller, it has been so user friendly and well organized than say the following other 2 websites I'm on such as Redbubble and Society6. I still love Redbubble, don't get me wrong. But Teepublic so far has given me good experiences. I would encourage it if you are a fan of anything to check out the site itself. Here is the link to my page if you are interested in purchasing anything.

They usually have sales on classic tees for $14. The site is better than buying a shirt or whatever from Hot Topic. You're supporting an actual artist. Speaking of supporting, since I am referring you to the site, if you decide to do so, for every purchase you are selling, I earn one dollar up to $1000. You still get your full commission, and I get my dollar for spreading the word. Click on this link if you would like to join.
