For example, one book that I have to get this semester is Frankenstein (the classic novel). I needed it for a class in SF literature. This book is in the public domain (and thus freely available online), but B&N wanted me to buy a $10 paperback.
Okay, I can understand their desire to turn a profit, but what is equally interesting is that they didn't offer any alternatives. I know that B&N sells an enhanced edition of this title in the Nook Store, but they didn't offer it. The same goes for my other textbooks. A couple were available as ebooks, but B&N never offered me the option of buying the ebook.
Update: Okay, the copy of Frankenstein is now showing in the college bookstore ($8). But the others are still not. Weird. Also, seriously, B&N? Eight bucks for a book over a century old?
So far as I can tell, the Nook Store is not completely integrated into the B&N College systems. That's a pity, because B&N is missing an excellent opportunity to recruit future customers - including some who are using their parent's credit card right now. Think of the money slipping through their fingers. It's also exceedingly odd, considering that B&N sees the college bookstore as way to sell hardware.
On a related note, I noticed this issue today because I was buying my books. My total costs were less than a quarter of what I would have spent had I bought used books in the college bookstore ($192 vs $44). My secret: I bought 3 books online elsewhere and checked another 3 out of the public library. Here is how I usually buy textbooks, in case you are interested.
P.S. Now that I've thought about it, I'm going to ask the professor to remove that particular title from the bookstore buy list, or at least switch it to optional. I'm sure most students would prefer to get a free copy online rather than pay for one.
