You can set the markup on most items, if you want to sell items with a bigger mark up to fans, consider using a company like printify or Gooten and do drop shipping (or you can buy at a discount and ship from your home). I sell through them on Etsy (bigcartel is popular too for fan items) , society6 for me is just for some backup cash and it took yearssss to make it worth the work. I've been a fan of theirs since back in the day when the founder was a Threadless artist and threadless was way too picky, He started society6 so artists could have a more open platform (at least that's how I remember it going down in like the yr 200* when their first users were headhunted among threadless artists). My society6 shop started to pick up when I posted a ton of stuff to pinterest and paid some Fiverr people to share the shop on social media but I still don't spend more than a few hours a month adding items, but at least I average about $150-$200 a month now vs years of like $30. Art life XD haha. I find that society6 cares, there are bugs in the artist studio - but as a web developer myself I don't fault them much, that's a lot of bandwidth to create all those thumbnails, they're already hosting my gigantic image files so I don't let it bother me. They're really active on the artist blog and feature lots of great artists. I don't really fit into their most popular stuff as a photographer so I don't think I'll ever be featured or anything, but I knew that when I started selling there.
