Where's the courtesy or are they scammers!

Bunch of times people think they are the only ones that count.When someone offers you a car or part for a price then you come back with-if that's shipped or ill give you x dollars you have said NO to his price.Its up to the seller to renegotiate if he chooses.This is not wal mart where there is an endless supply of original parts.I watched a guy at a swap meet,three different guys had A body pedal sets,one was quite a bit cheaper than the other two and the guy just couldn't understand why the two were so "GREEDY"!!He bought the cheaper set and was happy for a while until he found that he bought a /6 set-caveat emptor.Dont expect everyone to chase your dollars-someone else may have put theirs on the table
