Many people are rightfully concerned about purchasing from people on-line or where there are not "money back guarantees."
If someone is informed and believes that a poster is not telling the truth, as both a consumer and seller, I would appreciate someone taking reasonable action have the situation corrected.
I somewhat regularly purchase things on line: Not for convenience or price, but because there are things I would like to purchase that are simply not available locally even though I live in heavily populated S. California. For online markets to thrive, people must have confidence. Misinformation, mistakes, and/or outright fraud destroys confidence and ends up hurting the system for all players.
