I'm thinking about starting a business that sells used books. What are some of the pros and cons of doing so?

Pros:
 • You can make a profit by selling books at a lower price than they were purchased for.
 • You can find rare or out-of-print titles that may not be available anywhere else.
 • You can provide an opportunity to people who otherwise wouldn’t have access to books.
 • You can offer books in different languages, helping to expand your customer base.

Cons:
• The risk of buying secondhand books is that you don't know if they're still in good condition.
 • You might need to spend time researching each book before making a purchase.
 • There's always the potential for fraud with used goods.
