And, because UK is the best, there is another website you want to know: Bookdepository!
Without shipping cost, you can buy a lot of books (in English, of course) for very very cheap prices! I wonder if in UK it's normal to have such prices for books... If yes, I should live there. And, the site sells too some stationery. Labels, postcards, notebooks... you just have to search a bit. The "search system" is very messy I think, but not so bad.

Well, the problem is... To look at this map makes me sad! I've seen so little of the world! I really need to travel more!
For now, I'm planning to visit Palermo and Roma. What next? Who knows...
