<human>:  I have a question about the legality of Online Shopping in California. Why is it legal to buy a book online but not a car?
<bot>: The reason is that books are considered a “merchandise” and cars are considered a “service”. Merchandise is a product that is bought and sold for personal use, while services are provided to customers for a fee. Merchandise is generally considered to be more expensive than services, so it is more expensive to buy a book online than to buy a car.
