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 money quickly with minimal investment.
 • There is less risk than starting your own product or service.
 • You don't need to create any new products or services.
 • You can sell items you already have in stock.

Cons:
 • The competition can be fierce, as there are many other businesses selling used books.
 • It's harder to build customer loyalty because customers may not feel like they're getting something unique.
 • You'll likely spend more time marketing and advertising than if you had started your own product or service.
