Do your research. Check Kelly Blue Book for the proper price for the vehicle, including its mileage and apparent condition. Always downgrade the condition by one ranking for government auctions. Also, do some smart used-car research, such as checking Consumer Reports for reliability and the frequencies of particular repairs, and checking our road test information if it's a recent model vehicle.
Vickrey auction, also known as a sealed-bid second-price auction. This is identical to the sealed first-price auction except that the winning bidder pays the second-highest bid rather than his or her own. Vickrey auctions are extremely important in auction theory, and commonly used in automated contexts such as real-time bidding for online advertising, but rarely in non-automated contexts.
Dutch auction also known as an open descending price auction. In the traditional Dutch auction the auctioneer begins with a high asking price for some quantity of like items; the price is lowered until a participant is willing to accept the auctioneer's price for some quantity of the goods in the lot or until the seller's reserve price is met. If the first bidder does not purchase the entire lot, the auctioneer continues lowering the price until all of the items have been bid for or the reserve price is reached. Items are allocated based on bid order; the highest bidder selects their item(s) first followed by the second highest bidder, etc. In a modification, all of the winning participants pay only the last announced price for the items that they bid on. The Dutch auction is named for its best known example, the Dutch tulip auctions. ("Dutch auction" is also sometimes used to describe online auctions where several identical goods are sold simultaneously to an equal number of high bidders.) In addition to cut flower sales in the Netherlands, Dutch auctions have also been used for perishable commodities such as fish and tobacco. The Dutch auction is not widely used, except in market orders in stock or currency exchanges, which are functionally identical.
I wasn't aware that the TSA sold all of the stuff it confiscated! That's cheap goods right there! My mom works for a cruise line, and they don't confiscate stuff, but people do tend to forget all kinds of things they bring on the ship, so every once in a while the company has a big flea market available to employees. I find it funny when my mom comes home with watches and bracelets she wouldn't have otherwise bought.
