I hate flippers.
A few years ago i saw a very well known person in the mopar community, browbeat, harrange and generally whine about a rare part he wanted. The price asked was very fair, but this person hung around and hung around until the seller lowered his price, just to get rid of him
Minutes later, the very same part (very rare item, unquestionably the same item) was in well known mopar persons space, marked triple what the original owner was asking.
Okay, its worth more money. Then why did you have to beat the guy down some more, you prick!?! Pay him a fair price.
I have refused to buy anything from that prick to this day.
