BidSlammer did not bid on my item. I've had no problem with bidding on other items from the same seller, also I am able to manually date on the same seller's items.
This item was meant to the Christmas present which I missed.
I'm not sure how stable this platform is and should probably remain free until all the bugs are worked out. I was disappointed when the platform switched to only allowing 5 items at a time less than 1000 dollars.

Hello Paul,
Thank you for your question about this snipe. 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."
All we do is place the bid and report back the result. We can't control the errors eBay sends back to us.
If you were able to bid manually, it must have been before they blocked you.
We hope we have resolved this to your satisfaction. Please advise if we can help with anything else.

The name you submitted the ticket with doesn't match the eBay account your BidSlammer account you authorized with. Unfortunately, this is not only a violation of our terms, but also forbidden under our contract with eBay. We regret to say we have to close the account. You are welcome to rejoin using your own account.
Offhand, this may also be the reason the seller blocked you.
