That's funny, because I used to email people sometimes to tell them they were about to pay $xx.xx for a free emblem. Usually only for really expensive bids. I've contacted sellers too, just to let them know.
I recall one guy bid just over $75 for a 100K, 200K, and 300K badge "set". It turned out he was from Europe and couldn't get them easily, so there is a market for that kind of stuff.
