From what I can tell S6 has been around since 2009. Of course, I am always late to the game but I opened a shop on S6 there back in July 2011 but didn’t really start doing anything with it until December. I love that you can purchase different types of products! Where as on Etsy, I only offer prints, S6 has prints, framed prints, canvases, laptop & iPad skins, iPhone skins & iPhone cases. My bestsellers have been the iPhone cases. Here are a few of the bestsellers

Too bad I don’t have an iPhone!
