Completely replicated? No. However, many publishers are working to create situations like that one in the ebook field.
First, some publishers -- Baen and Tor for example -- offer free ebooks to get you interested in their writers and series. Baen is the largest I think in this field of letting you sample whole books with their
Baen Free Library. I have sampled many and gone on to purchase many more. Some I had heard great things about and did not care for the writer's style or the characters. Baen saved me a lot of remorse in the style of "why did I ever purchase THAT book?" Other free selections have started me on the road to reading everything they offered by the same writer or all of the books in a given series. Tor has a program (or had a program, I am not sure where it is at the moment) that would give away a complete book every so often to those on its mailing list.
Many ebook sellers -- like Fictionwise -- offer an extended extract of the book for you to read before you buy. Some worked. For me many were fair warnings that this book was not one for me. Result, a happy repeat customer.
There is also another place, the MobileRead download area. These are completely free (depending on the copyright laws where you live.) You may download them, pass them on to other friends, and generally do with them anything you could do with a pbook except resell it. They are not this week's top 10
New York Times sellers but they are excellent books, well produced, and with a full money back warranty.
