OP established a finish time and also put a counter. (If it was ebay, i would have won).
OP did not try to contact me, i even sent him a message right after the end of the auction to contact me for details, which he did not.
This part of the forum does not let you edit your posts, the happens for a reason.
If he was not happy with the price, he should have put a reserve price.
If a person is willing to do this type of moves because of one or half btc for sure is not one i want to deal with.
I hope that at least one moderator gives a word about this, if not i dont know why there is a auction section if the people that put the auction up does not follow there own rules..
If i had won and did not pay for sure someone will come and call me a scammer and whatnot, what he did was the same from a sellers perspective.
Although Maged gave his view above, I would agree with you that this is a form of bad business practice to be renegading against one's own words here, especially when I had first hand experience of dealing with auctions here (I was the auctioneer for the AM blades). This is an auction for a reason - the seller is expected to fulfill his end of the contract here. I wouldn't blame you if you posted a thread about this in the scam accusation subforum to warn others about this.
