on the surface, appears to be a nice idea... but..

if you put up 50, sell only what someone needs, and are undercut, the remaining ones wont sell, until you lower the price. it could be up there for a while as you are being undercut by others as time goes on and theirs gets purchased over yours. That will play havoc with the open market spots on retainers. Or are you also suggesting they set the pricing as well?
