i thought i was going to tell you since it could be a great opportunity. Book Depository ( uk version) is doing a special offer. During 24 hours ( starting in less than one hour ^^;;) there will be one book each hour with a great saving on it. Each hour we discover which book and it lasts only one hour or until this book is sold out.
Perhaps you will find the book you really want, anyway, i thought it could be useful so go there if you have the opportunity to do so.
