Opening a bookstore required consideration of the cost of buying books. Different sales channels had different costs. A common method was to find new book suppliers online and contact them directly to get discounts. Many online bookstores would offer discounts on new books, sometimes even lower. Another method is to look for new books at the local wholesale market or book market. These markets usually have a large stock of books and can buy books at a lower price than online. However, it was necessary to conduct sufficient research in the local market to determine which books were most suitable for local sales needs. Lastly, you could consider working with other bookstores or editors to get discounts or share stock to reduce your own costs. No matter which method was chosen, one had to pay attention to the control and management of the book inventory to ensure that the bookstore had enough books and would not be overly dependent on certain types of books.
