Second, Dangdang, many people recommend Dangdang to me. It is said that the discount is very cheap, and all the books are true. Compared with Taobao books, the quality is much better. I bought it several times. The price is not very affordable, but the quality is really good. Just like JD.COM, you can get a discount. If you encounter a discount, you should start quickly, otherwise it will be easy to miss it. You can also make a group. If you need books, compare them as much as possible.
Third, turn to second-hand books. There is a function on WeChat that you may not care much about, that is, turning to second-hand. There is a second-hand book in it. If you have any books you want to buy, you can find them in second-hand books. The price is very cheap, and it will be mailed when it reaches a certain amount. I have bought books on it several times, and the quality of the books is very good. I will also wrap them in plastic, just like the new books, but the price is higher than the new books.
Fourth, the library, I personally went to the library to read books and got a library card. Children can borrow six books, and I can borrow six books myself and return them within one month. If I don't finish reading them within a month, I can put it off. The library has blue light disinfection. Just sterilize the borrowed books with blue light. I think this is the most affordable, and I can read books without spending money.
