Sale on O'Reilly ebooks today

O'Reilly is having a one-day sale on ebooks: $10 each. I've just picked up "Python for Unix and Linux System Administration", "Python Cookbook, Second Edition" and "Python in a Nutshell, Second Edition". (Detect a pattern?) They're DRM-free, the way Cory Doctorow intended. Downloading is a little slow right now, but I imagine that's just because of increased sales.

I'm not a shill for O'Reilly, just a satisfied customer. (Mostly. I wish OnLAMP.com was getting a bit more love.) (But then, I'm not paying for OnLAMP, am I?)
