Impulsive Shopping

I read recently an online article named "5 Sneaky Mall Tricks." It detailed ways that shopping malls work to get us to spend more money than we originally planned.

One of those ways was putting escalators far apart so that you have to walk past more shops and items in order to get to the next escalator. In doing this, we will pass by items we didn't come to buy and buy them anyway.

Boy, we sure are easily manipulated! But we really shouldn't blame them--it is the materialism in us. Why do you think we are so impulsive in buying?
