For active buyers, Amazon is a cheap and fast way to replenish your digital book library. In addition, if during the announcement of the Amazon service it talked about 10,000 books participating in Matchbook, then today their number is an impressive 70,000 item. New books are added to the program daily.
Now in the details of a particular book on the Amazon website it will be reported whether it supports Matchbook or not. Amazon has been accumulating the entire story of the purchases of a certain user since 1995, so the list of offered discounts for perennial users of the store can be quite impressive. Moreover, books support all Amazon functions like Whispersync and X-Ray.
