Buy books in the internet

Today I recieved the books that I bought from the internet the day before yesterday. I bought four kinds of books to my daughter. It took me 122 yuan to obtain these books. I think it's valuable.

Although these books were sold at a half discount. But I find these books are very interesting and very helpful for my daughter. So I think I have done a correct thing. I'm very happy. I have no experience in buying books in the internet, this is my firt time.

I will continue to buy books in the internet, if only these books are helpful for me.
