Since my bid slammer bid was 11.11 why did I not win this since it went for $5.95. Did bid slammer fail to react? Was I blocked for some reason?

Hello David,
Thank you for your question about this snipe. The result is shown on your "Completed" tab.
When we placed your snipe, eBay returned the error, '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.'
We cannot get past hard blocks, unfortunately.
We hope we have resolved this to your satisfaction. Please advise if we can help with anything else.
