Amazon just announced a new program entitled Kindle MatchBook, “giv[ing] customers the option to buy—for $2.99, $1.99, $0.99, or free—the Kindle edition of print books they have purchased new from Amazon.” MatchBook will include purchases made as far back as 1995, so you are officially out of excuses when it comes to cracking that lofty, intimidating TBR pile in your house.
