Twice in the last several months, I clicked the "One Click" button only to have Amazon tell me “You have already bought that one”.
I am of the age that memory fails me as to when I bought or even read something, and I can happily read it again; for FREE! As a matter of fact, it just happened yesterday. I started Kim Harrison’s “The Hollows” series, and when I got to the fourth book, it was FREE!
I'm half way through da buggah, and I have no idea if I've read it before or not.
