Do Sales Actually Save You Money?

When you go to the mall, you are bombarded with advertisements and companies saying they save you more money. And of course, you think that all of these sales will actually save you money. But in reality I don't think they actually do. Take Bath and Body Works for example. They sell things like, buy three get three free. This is crazy, who would need three bottles of lotion anyway? Let alone six. We trick ourselves into thinking we need things when we really don't. Companies do a great job at this, they tell us that we would be able to save money on things. We, the consumers, convince ourselves we need that thing/things and buy it. And when the deal is done, realize we bought too much or in reality didn't need that product in the first place. We don't usually realize we don't need the product. Instead we pat ourselves on the back and tell ourselves we made a great deal today. I have also made this mistake many times, always forgetting that the company doesn't have my best interests in mind when selling a product.
