It was common for bookstores to sell books at a discount. Under normal circumstances, bookstores would regularly carry out promotional activities such as discounts and full discounts to attract more customers to buy books. However, the specific discount intensity would vary from bookstore to bookstore. Some bookstores might be more aggressive, while others might be less aggressive. Whether it was cheaper to buy a book in a physical store or online depended on the method of purchase. If you buy in a physical store, you need to pay in cash or use a bank card. If you buy online, you can use AliPay, Weixin Pay, and other electronic payment methods. Therefore, online purchases may be more favorable. In addition, online purchases could be conveniently delivered to the door without the need to bring books, while physical stores required walking or riding a bicycle to buy. To sum up, it was very common for bookstores to buy books at a discount, and the way they bought them depended on their personal preferences and needs. No matter which purchase method you choose, you can get the best price according to your actual situation.
