Pearson is doing their annual "Back to Business" sale until Monday, September 19. You can save 35-45%, which is a big deal IMHO.
The Practice of Cloud System Administration is 35% off, or 45% off if you buy 2 copies. Buy one for yourself and get a copy for a friend for their birthday. Just use this link to receive the discount.
You can also get a copy of the Cloud Administration book plus the new 3rd Edition of The Practice of System and Network Administration (when it ships in November) and save 45% if you use this link and enter offer code "B2B".
These offers end on Monday. Act now!
(NOTE: I'm not saying our books are great birthday gifts. However think about it this way. What's the worst that could happen? If your friend is offended and never talks to you again at least you'll have more time to read your book. Isn't that what you wanted in the first place?)
