I have no idea why Cafepress has done this or even when but from what I hear it is a recent development. It wasn’t all that long ago that the link was removed. To be honest I wouldn’t be all that surprised if it were taken down again soon. You can see the image below to find out where the link is. There are two similar links on the page. The one on the left is to see all the shopkeepers items in the marketplace but they are unsorted and probably don’t lead to many extra sales for Cafepress. The problem now is the price disparity. The Cafepress marketplace items are generally (not always) cheaper than in the shop. In some cases the marketplace prices are even lower than the base price for the shopkeepers so it is impossible to compete on price (and pretty difficult to compete on marketing). Anyway, it’s better for the shopkeepers to have this link than not to have it.
