How does one person spend 3500$ on a 180$ tablet: write a bot. You tell it to "buy any item at ≤10% retail price if the remaining time is ≤1s". Sounds reasonable, even if you pay a few cents for the losing bids, right? ;)

Each time someone makes a bid on your penny auction have the bot automatically make a pretend bid using a fake user. When people finally stop bidding, make a final bid from another fake user that has never bid before and win the auction for $0.80.
Unless you are the person running the penny auction. In which case, keep sniping until people stop paying and then have a final fake bid to win the auction.
