So here's a hypothetical situation. Let's say I've downloaded a free book as a kepub to my touch that is a limited time offer. Down the road it goes back to being it's normal price. After reading it I delete it off my touch and sync it so that the book is no longer in my library. Later still I decide I'd like to re-read said book but the epub I downloaded through ADE has become corrupted. Will I now have to buy the book at full price to read it? I doubt this will ever happen since I always download my books and backup the epubs in a couple of different places but just thinking ahead to some catastrophic failure of all backups simultaneously. Thanks for any info.
