I've just about given up on making 2nd chance offers. As a seller, I have made many 2nd chance offers, and have been shocked that they don't buy or even reply. Maybe it has something to do with familiarity breeding contempt -- that they like the excitement of an auction, but if it is simply offered to them, it loses its luster, or they think maybe it is too common (that the seller maybe has a million of them). As though the first auction was the only one in the world. It's quite strange. Then there are the reasons mentioned -- fraudulent email, and shill bidding.... ..... ..... Another thing that surprises me with buyers is that they never (or hardly ever) email me before the close of an auction asking how many of the chip I have or know of. .as though they are afraid or no reply or a saecastic, caustic one. ..... Also, lately 15 people can be "watching" an auction, and only one or two end up bidding.
