We are wholesalers. Generally, novels are 4-5 fold, only 68 fold for Jin Yong and 72 fold for February River. Nothing else is too high. Teaching AIDS are 50-20% off, so it seems that small bookstores want to make money, and all the books inside can't be genuine.
Want to know if it is genuine, directly reduce the price and find a book with acceptable quality. If it can be sold at a price below 20%, it must not be genuine.
