Cameras for Lenses

So I've decided to offload one of my cameras and a few lenses so that I can afford to buy a couple of prime lenses for my 5D. The 7D is an exceptionally fine camera and excels at a type of photography that I don't really do very much of. Sports. So it seemed a no brainer to put it up for sale and order the new lenses. Except nobody seems to want to buy it! They've "liked" the photo (such irony), but when it comes to cash...once more my path is strewn with cowpats from the devil's own herd.
