Car dealers are beginning to advertise "buy one get one free" sales. One men's clothier is running a :buy 1 suit and get 2 free" ads. But, you may end up with fake bargains.

Case in point, a supermarket built a pyramid of chicken noodle soup and hung a sign on it that read $1.95 a can. Most consumers thinking that sounded too expensive didn't buy any. The next day the store added a new sign to the pyramid that read "Maximum 8 cans per customer." All of a sudden a line formed to grab the same $1.95 cans of soup!

If you don't think stores employ psychology to lure you into buying, think again. A $2.50 item that has a 2 for $5 sign speaks to our inate desire to hoard goods. Since it is a throw back to our Stone Age ancestors when food sources were scarce, any sale that triggers the fear this titem might not be available again or at least never available at that price again becomes an absolute necessity. So buyer beware!
