Bad dealings with Superbeesrt8 Beware!

This almost sounds like your saying that unless a seller get his full asking price, he doesn't have to stand behind his product...that c ant be what you meant, can it?
No.
What i mean is that if you talk someone down on their price, the patience from the seller wanes a bit sometimes to the point of 'what the hell do you expect from me?''
We don't know what was ACTUALLY said between the two parties on the sale.
All i can say is if it were me buying something like used heads etc. for over a grand, i would want to see them in person, other than that, you are taking a chance that they are good to go and complete.
And let the chips fall where they may especially if they are sold at a discount.
It still doesn't make it right for the buyer to be disappointed and blown off by the seller.............
This is precisely why i rarely buy something or sell something for that matter unless i can fondle it and look at it in my own hands before i buy and i expect the buyer would want that too.
There is a fine line in perception of the quality of a part vs value paid for some people.
However, If you stand behind your product regardless of the agreed upon price, and do all it takes to please your customer, it speaks volumes about your integrity.
