I'm still surprised they get away with selling e-books at the same/more expensive price of their paper counterparts.

The "old" way to sell e-books was to use what is known as the wholesale model.

The books in the Free Library are available via the website for Baen Ebooks, which also sells individual e-books and a subscription-based e-book program.

It was implemented by Baen's preferred website expert, Arnold Bailey, who also sold e-books for other publishers.

Until January 2012, Baen sold e-books through Webscriptions, which was established in 1999.

And so, capitalizing on its "first mover" advantage, Amazon sold e-books at prices conspicuously lower than physical books-many titles were made available for $9.99.

Apple merely acts as an "agent" for the publishers, selling e-books at whatever price the publisher sets.

Prior to Apple's launch of the iBookstore, publishers typically sold e-books to Amazon or other resellers at a specific wholesale price.

Independent booksellers wondered if they should focus on selling e-books, in addition to physical books, as some have proposed.

After selling 10 $50 e-books, the organizer has made $500, and can purchase a PS2 for $299 to send to the first bidder while retaining a $201 profit.
