What amazing timing! The ebook
just went on sale today for 50% off (and the sale lasts for the week).
Edit: So, it was mentioned that this looks like a spam message (and now that I look at it again, it really does). However, there really is a sale!! And it lasts all week!! And it is for ALL of O'Reilly's perl books!!! (You just have to wire a modest sum to a Prince in Nigeria and then we can unlock the coupon codes from the bank vault...). Seriously though, even-numbered pages are free all week long.
