What's sad is that these tendencies can be exploited (see attached pictures in my original post) and that we'll subject ourselves to all kinds of stress with regards to deal hunting just to find a bargain that might not end up being a bargain.

And while I know that humans aren't rational creatures (in fact it was my research for a number of years), some of this can be fixed with market leadership and "training" customers to understand that they're acting against their best interest by demanding an economy in which marked prices are in fact price anchoring deceptions.
