What is the difference between buying books in a physical bookstore and online shopping?

Go to the physical bookstore to buy more books, enjoy the process of choosing and feel the atmosphere. It doesn't mean that I really went for this book, except for the period when I was particularly nervous in senior three, which was to buy five years of college entrance examination for three years. At other times, there is no obvious purpose to buy books, just like reading some books on psychology, behavior or history and going to the bookstore to pick one by one. After reading the general content and introduction, I found this book very interesting and bought it. I don't have a particularly important purpose, but I enjoy the process of choosing. If I bought it online, I have a strong purpose. I just wanted to buy a book, and then I chose which online merchant was cheaper, and then I chose this one.
