This seller has no morals.
I don't think the buyer would be the same or related to the seller. With some of those notes going for such high prices, the eBay gets a cut of the selling price. So, by looking at the several auctions that ended, the fees to eBay would be nearly $100.
I have a feeling that perhaps the buyer is doing it in spite, knowing that the notes are not worth what the seller is selling them at.
Actually, the BUYER has PLACED NEGATIVE FEEDBACK and made warnings about the seller.
Whoever the buyer is... that's fantastic!!!
