Do you make money by selling books by SMS?

Personally, I think it is difficult to make money by selling books online, because things on the Internet are lower than the market price, and the profit of books is small. Unless there is a bookstore or publishing house to rely on, you can get goods at a very low price. Secondly, Excellence is b2c, a professional online book seller with high popularity and low price, which brings considerable pressure to other online book sellers. I recommend the landlord to sell some women's and children's products and novel products, which are very popular. Online.
