“

On Tuesday, the company plans to announce a new program, Kindle MatchBook, that lets its customers buy the electronic versions of books they have already purchased in print form for either $2.99, $1.99, $0.99 or free. That’s far less than the $11 or more that Amazon typically charges for standalone purchases of the latest Kindle titles.

One benefit of MatchBook is that Amazon will let its customers buy Kindle editions of books that they purchased in print as far back as 1995, the year Amazon opened for business. The discounted Kindle edition prices apply to book purchases made in the future on Amazon too.
