Every day, we see hundreds of ads on TV and online. Companies advertise their products everywhere because the market is very competitive. However, a famous brand does not always mean better quality. Before you buy something, ask yourself if you really need it and if you can afford it. Compare prices in different stores and look for a price reduction. Always keep your receipt in case you want to return the item. Also, try to choose products with less wrapping. Smart shoppers save money and help the earth at the same time.

Last year, the students at my cousin's high school started a cooperative shop. They wanted to sell healthy snacks at fair prices. First, my cousin and her classmates had to negotiate with a local manufacturer. The negotiation took two weeks, but the company finally lowered its prices. The students also started a poster campaign to tell everyone about the shop. Now the shop is a small enterprise that makes money every month. My cousin says she learned more about commerce there than in any class.
