David,

I have been know to tell someone they undercharged me for something. But not always.

I do however tell people when they are overcharging me. At least when I catch it.

I was at a garage sale the other day and saw a group of cds. 5 full cds and 5 singles. I asked how much they were. The person said $0.10 a piece. My face must have lit up like a christmas tree. I gained my composure and when and picked up the $1 and paid them.

I will probably keep only 2 of them. Still a heck of a deal.

A few year back I bought hamburger but was not charge for the cheese on it. I went back into the the place and gave the waitress the extra $0.50.

I guess it just depends on what mood someone is in whether they jump at a deal or nicely inform the person that the asking price is to low.

Just my 2 cents.
