Hello Chris,
Thank you for your question about this snipe. To see why you didn't win an auction, visit your "Completed" tab and hover your mouse over the error icon.
The error returned by eBay is: "Unfortunately, this seller has decided that you are not permitted to bid on their listings. You may contact the seller via the "Ask Seller Questions" feature if you want additional details."
You most likely have an account condition that is triggering the seller's Buyer Requirements.

I hope this has been resolved to your satisfaction. If you have additional questions, please don't hesitate to ask.
