Anyone who purchases a docking station, can opt to have a new AC adaptor (power supply) shipped along with it for US$11 extra, S&H included. EDIT: Or more than one, if you like, at US$11 each.

This is only for new dock shipments, so if you want a power supply, just sign up for another dock!

Sounds like "you can get one without a docking station by buying and reselling the docking station.
