I was in a store ready to check out; there they were candy bars just waiting for me to take them home. Why do they even put them at the checkout! Well, the store knows that almost everyone has a tendency to "impulse" buy. In fact, some stores set a place aside for the things they think you will pick while you are looking for other things. The problem with this type of buying is that we forget that little things add up. We may pop it in the cart and think, "it's just $5"; what we forget is that if we add even a couple of things, we could easily spend $25 quickly. Then we look back and think, "where did that money go." Who among us has not walked into a store with the idea that we were only going to buy a couple of items only to find that we have actually bought way more than the "couple of things". In my case, they are often things that I want, more than things I need. I get deceived because they don't cost much, so it's oka
