Let me explain and the backpedal a bit.....
It seems a bit odd for a person with one feedback to just pop up out of nowhere and place a bid like this on a book like this. If you look at the history, the bid was placed early and was obviously very high as everyone that bid was just outbid by this person. Also, at $416, the book sold for almost as much as a comparable book on abe would sell for (there are two exact same copies for $450 on abe). I've been on ebay for over 10 years now and seen all kinds of trickery especially involving using shills to bid up the price of items and thereby protect them from selling for a price that the seller is unwilling to sell them for.
Still, the buyer is in Spain, so in fact it may be 100% legit. It would be pretty damning if the buyer and seller were in the same location (The seller is from Goshen, NY).
So, on second look, it looks more legit. Maybe we have a new Bukowski fan in Spain? Maybe this is someone that has been collecting a while, but just signed up on ebay, or opened up a new account.
The thing that I watch out for is a situation like this, but one where the exact same book pops up a month later (sometimes you hear that the buyer backed out, sometimes nothing). Another method is to have the shill bid the book up to a reasonable price and then contact the #2 bidder and say that the buyer backed out and that you will sell it for their bid price. Seems like a deal, unless you think about and realize that if the winning bidder kept out of it, the bids would probably not have gone as high. This is a way that a seller, using shills can drive the price up and get more than they would in a fair and open auction.
I had a person that is a well known bookseller (and one that dealt in Buk) sell me something on ebay. It did not arrive. I waited a few weeks and then called him. The ebay account gave me the name & number of the person that I knew well (Or someone else with his same last, uncommon name). I realized that not only was he the seller of this book, but actually was the number two bidder, having driven the winning bid price much higher than it should have gone. This type of bidding is illegal in many states and countries as it is considered fraud.
Still, the auction of "Burning in Water" does not seem to be a case like this. I probably typed too soon....
Plus, this seller was the one that sold the copy of "At Terror Street" a while back for $203, so it seems that they have a few really nice, early books!
