Why I haven´t won this auction? There is several I have found where my bid is higher than the winning price but my bid wasn´t placed. For this auction my bid was 22USD but the auction ended with winning bid of 12,5USD

Hello Vojtech,

Thank you for your question about a snipe. The pattern you describe sounds like you are being outbid by proxy bids.

You can see the error that eBay returned:

1. Go to your Completed tab.
2. Verify snipe placement times listed.
3. Click the "log" icon next to your snipe.
4. Review the full execution history.

If there is an error returned by eBay, it will be shown on the Completed Tab and in the above execution history.

I hope I answered your question to your satisfaction. Please let me know if I can help further.
