Hi welcome to listia . I'm assuming your either new or semi-new. You cant really end auctions once bids have been placed. Also 499 isn't gonna win the auction the highest bidder will win the auction and apparently it's around 4,000 points right now. But good luck I hope you get a good amount of points for this
I'm new and I've already figured it out, And yes I'm fully aware of the current high bid but it was stuck at 1 points for like a week and with my luck... someone winning it for 1 point seemed very likely xD
