Consumer groups are organizations that advocate for the rights and interests of consumers. They work to ensure that products and services are safe, fairly priced, and of good quality. These groups often conduct research, publish reports, and provide information to help consumers make informed choices. Additionally, consumer groups may engage in lobbying efforts to influence legislation and regulations that affect consumer protection. They often collaborate with government agencies and other organizations to promote fair practices in the marketplace. Examples of consumer groups include the Consumer Federation of America and Which? in the UK.
