Is this the case for you and price promotions

I find this is true in my personal life and have trusted it in my professional life. Was wondering if anyone felt significantly different. When you cut price you expose the true value. Hard work needs to be done on what the particular price should be and then it should be stuck with, at least if you are passionate about it. The things I buy on promotion are things that I don't care about. When I pay full price I am nuts for it.
