There are also reverse Dutch auctions which you bid to drive the price down. The winner ends up paying the remaining cost of the item. You buy a bid for 50 cent

There are also reverse Dutch auctions which you bid to drive the price down. The winner ends up paying the remaining cost of the item. You buy a bid for 50 cents and the bid drives down the price by 2 cents. If the remaining item is $15 for a $2000 item. You pay $15. It's all a scam tho imo.
