A consumer is  a person or organization that uses economic services or commodities. In economic systems consumers are utilities expressed in the decision to trade or not.
A consumer is anyone who acquires goods or services for direct use or ownership. All consumers should learn how to do simple things like manage a credit score, read the fine print on a gift card and understand the importance of choosing a secure email password. It's also important to know when the law is on your side and when to contact an attorney to help you enforce your rights. Organizations and agencies like the Federal Trade Commission and Better Business Bureau promote and sometimes enforce consumer protection laws.
