Not to take away from folks buying from Amazon or direct from the
Pragmatic Programmers, but I think this is a pretty good price for

There are a number of other very good Ruby books for very decent
prices! For instance, the Ruby Cookbook:

That's going for $30. Wow.

Hope this helps someone, and doesn't hurt others.
