That concludes this insight into the world of marketing. A lot of this came from author's own experience while operating a CafePress shop, Zazzle shop, looking for commissions, and being a member of all the mentioned art sites (as 'liiga', on each and every one of them). The author doesn't claim to be perfectly knowledgeable on the entire issue, and there are most likely tips and tricks that have gone unmentioned, and some information is likely to change with time. Hopefully this article will provide useful in your travels through the art market. :)
