Folks, the snipe tool is apparently misbehaving. Per reports from Romeo and Matt some auctions they should have won didn't go through even though the tool says they won it. While I have the programmer look at this please consider doing a manual snipe if it's an important item you're after. I've had about a dozen successful auction wins this past week but I myself am not trusting it.
Will report as soon as my programmer can tell me what's going on.
