So I just wanted to say I have found a good site for buying books on the internet. It's actually an Irish bookshop but they offer free worldwide delivery and have over 5 million books in stock. I just recently bought some books from them and am very happy. It's also safe to say that the majority of their books are quite a bit cheaper than Switzerland. Their site is here Kenny's Irish bookshop

check also http://www.bookdepository.com/ they have better prices than amazon a free shipping.
