Prentice-Hall International-UK made a mistake in the online offer made to TidBITS readers for my book. They have been offering 20 percent off 18.50 pounds, when in fact the base price they should have been charging was 27.50 pounds, which is now in effect. Sorry for the mistake, and if you lucked out on the lower price, congratulations.
