who is in on " first strike your out" rule?

I'm not defending or backing your point of view but just wanted to point this out. Using the example of the tach for 275, whats to say that person didn't know about the repops? Or let us say that instead of just that one tach for sell 4 other people are selling original ones for 100 to 150 and someone points that out to that person. This way the person can take into account for the current market value for them. Its all about supply and demand and then adjusting for that. Again maybe that person just didnt know the current market for them and someone was just pointing it out. Be I can see you point though (I would've PM'd him myself though).
