If a site costs $140 a year and you make $2 in the year, I suggest not keeping it. :)
Also, FAA is so much easier than most sites to make a purchase. The options are clear, the prices are clear, and placing an order is a snap. Some sites requires many clicks just to find an option to buy; that discourages purchases.
I dropped Cafe Press after several years because they made changes that ruined the experience and all but eliminated profits. I have not gone back to Zazzle yet, but may in 2015.
I point people to my urls at sites like Flickr, ViewBug, StumbleUpon, Pintrest, Google+, Facebook, Twitter, LinkedIn, and others - that will now send them all here.
I do think that one site for selling is better than several from the standpoint of not confusing the consumer. I also understand that many sites may mean more hits which may lead to more sales.
