I don’t know how widespread this is, but a couple of the Barnes & Nobles around Denver have the nice trade paperback sized Associated Press Stylebook on the shelves in the clearance section for $5.98 which is a heck of a deal. If you are a freelance writer, sooner or later you are going to need the AP Stylebook and at this price, it is cheaper than buying used. So, if you find yourself in Barnes & Noble in the next week or two, swing over to the clearance section and look for it.
It looks like this (its at Amazon for $12.98 )
