This is actually a psychological imbalance for students, because for students or many people who like reading, the price of buying a new book is still very expensive, which means that the value of books in this society has not depreciated. But when you sell books, you can only weigh them by the catty. For those books and rice, taking away these books that were originally bought at a high price is like collecting junk.
But even so, many people can only choose this way to deal with too many books at home, because this is the way to deal with old books in this market now. Many people sell books with gold, not because he doesn't care about the value of books, but because he wants to get high prices, but there is no way. This is not for the seller to decide, so the price of those old books does not represent the actual value of the books, but a way for people to deal with them.
At the same time, these books bought by pounds, renovated or treated as second-hand books, will be sold to readers at higher prices. But this process is beyond the control of ordinary people, and it needs to form a marketing system. This is how second-hand booksellers make money.
If you are a fresh graduate and it is expensive and troublesome to take these books home, then you can only choose this way of selling by the catty. But if you are not in a hurry to deal with these books, you can put them on the second-hand website one by one, which is better than selling them by the catty.
