Penny auction apps like dealdash, they always have bots that will outbid you so you can never actually win one of their auctions. If you do win an auction, you're not actually guaranteed to ever the see the product you won.
Both this, and that winning an auction doesn't get you the item but the ability to pay for the item. The "penny" refers to the fact that you pay to buy bids in the auction, not that you pay pennies for items.
