Hi RickyM,
Please don't forget to respond to Post 108.
I know it got kind of buried with excitement of your free samples.
People who accept samples please be careful with the law of reciprocity.
Reciprocity in social psychology refers to responding to a positive action with another positive action, rewarding kind actions. As a social construct, reciprocity means that in response to friendly actions, people are frequently much nicer and much more cooperative than predicted by the self-interest model; conversely, in response to hostile actions they are frequently much more nasty and even brutal.
Its used in both Sales and Psych warfare.
