I might look into that but I'm not sure it's worth it as I tend to binge read for a couple of weeks than read nothing for a while; there's no pattern to it.
I just buy them. The lending thing is only one book a month isn't it ? When I get going on an author I tend to do all their books; I'd hate having to wait 3 weeks for the next one.
I've got the button on my old keypad kindle but not on my ipad. I tried changing the ipad to default device but still nothing so I suspect it's a app issue.
