To all the readers here, I have only one question for you. Have you ever wondered, why you buy more than you intend to? The truth is, you are a victim of something called as up-sale. Simply put, up-sale is where the sellers encourage the consumers to buy more. What happens here is that the consumers are indirectly pressured to buy the better product. This in-turn will lead them to spend more and the producers to earn more.
