Got the BFC children's book club stuff in the post this morn - you know the type "Any 5 books from only 50p each! And then buy four more books during the year". Does anyone use this book club and what are the pros and cons? I don't want to be saddled with a load of expensive books that I don't want but the offers do look very good. There is no contact phone number for the company which I always find a bit suspect...
