Thanks to mark for this link …. the idea of txtbux.co.uk is that you can text any book’s ISBN number to the service and get a message back telling you how much the book is on Amazon.
That’s great for anyone who regularly buys new books, but where I’ll find it useful is in keeping a record of books I’ve seen that I’d like to read – there’ve been so many occasions where I’ve seen a book in the supermarket or Waterstones, haven’t been able to afford it but have scrawled the title and author down on a bit of snotty crumpled tissue or old till receipt so I can look for it in the library or on eBay or (more likely!) on BookCrossing – and have then thrown away the bit of paper. Now I can text the ISBN and get both a text and an email to remind me what that fab-sounding book I saw was called!
