Why did my snipe not execute and it was moved over to “Completed Snipes” section, but the auction was not even close to ending?
This is because you are placing the snipes in a bidding group. When one of the item from the bidding group is won, others are removed from the pending queue immediately, with the status “Didn’t bid”. Learn more in our manual about bidding groups, and when you need to use them. Do not use bidding group for ALL items you must win!
