Most of the good and services are available in the market do not reflect its real value. This is a good opportunity for sellers to earn excess profit where consumer is getting worse off. You may also have such a experience where you may have cheated by sellers by selling their product at unreliable price.
If you have any experience like that could you share your idea and I will be highly appreciated if you could mention any suggestion to avoid this malpractice made by sellers and it will be effective to certify the consumer well being.
