For those of you who don't know what cpshop is you don't have anything to worry about but if you have cpshop installed you may want to check your add to cart prices. I found that even though the prices displyed in my cpshop were the markups I had set, when they were added to the shopping cart they reflected the new marketplace pricing which means I as a shopkeeper would earn much less per sale than I should.

If you have a Cafepress shop and intend to continue using it I highly recommend cpshop which was made by a guy called Marty. It allows you to pull your whole store into your own domain. There are some issues at the moment because of the marketplace pricing changes but hopefully Marty will fix them and update his script when he gets back from wherever he is.
