Second, first of all, the quality of the book is not bad. The material and cover color of the book are the same as those of the bookstore. It should be a genuine book, but it's cheaper than the bookstore.
Third, books that can't be bought by bookstores are sold in Amazon.com, especially foreign classics. Some small bookstores don't have them, and there is no big bookstore where you live, so it's convenient to buy them on Amazon.com. ..
Fourth, the customer service attitude is not bad. I bought a book before, but suddenly I don't want it. I asked the customer service to return it. The customer service agreed without saying anything, and patiently instructed how to return the goods.
