People sell things at many different places. Farmers sell fresh fruits and vegetables at markets, and bakers sell warm bread and cookies at bakeries. Some people even sell things online so you can shop from home! When you buy something, you trade your money for a good or a service. The buyer gets what they wanted, and the seller earns money for their hard work.

• People have been buying and selling things for thousands of years!
• The first stores were outdoor markets where people set up tables to show what they had to sell.
• Today, some of the biggest stores in the world are on the internet, where you can buy almost anything without leaving your house!
