Unfortunatly, you cannot but the books online at officedepot.com (Which makes no sense).. Yesterday I went to my local Office Depot and I found 22-23 books for 99 cents each. ) They weren't in the front of the store, nor where the other Dummy books were, where the OD worker led me.. They were by the home phones in a short stand up bin. Mixed with iPads and Facebook for Dummies I believe.
I've heard of Target having them, but I have been looking at my local Target for several months and no luck.
