Last week you and a friend went to an electronics store. you purchased a television for $600 and your friend bought a video game for $40. today you saw in the newspaper that the electronics store was having a huge sale and your television is now $580 and your friend's game is $20. you decide it is not worth it for you to go and get a price change, but you call your friend because you cannot think of a reason why he/she would not want to go and get a price adjustment. the potential savings for you and your friend is exactly the same so why might you assume your friend would want a price adjustment when you did not?
