Yes, if you order books at the post office, they are ordered at the original price of the books, but they are sent to your mailbox or the place where you point. If you go to the newspaper, some of them can be discounted, but they are usually mailed to you. The post office usually puts your mailbox in it. If your mailbox is big enough, there is no problem. If it is small, it can be folded and put back. If there is no mailbox, sometimes it will be given to your doorman!

The difference between the two methods is that if you book at the post office, it may be more expensive, but you won't lose it. Even if you lose it, they will help you get it back. If you book in a newspaper, it's cheaper but a little unsafe, because they are surface mail, and you may have to pay more if you want to register.
