The District of Columbia now auctions its surplus property online through GovDeals, a Liquidity Services, Inc. marketplace. The district awarded the contract for the management of the inventory, appraisal, sale and shipping of the city's surplus property to Liquidity Services Inc. LSI conducts auctions of city assets such as vehicles, police automobile accessories, computer equipment, radios and other communications equipment, office furniture and other supplies through its online marketplace. The auctions are expected to improve data tracking and financial oversight of the city's surplus asset disposition activities.
Depending on the agency, the government may use revenue from auctioned items to support crime-prevention programs, pay restitution to crime victims or purchase new equipment the department needs. "By providing agencies with the ability to dispose of excess assets, GSA benefits taxpayers by eliminating the need to maintain and store the unneeded property while also raising more than $300 million in revenue in just the last two years," a GSA spokesperson said. 

Combinatorial auction is any auction for the simultaneous sale of more than one item where bidders can place bids on an "all-or-nothing" basis on "packages" rather than just individual items. That is, a bidder can specify that he or she will pay for items A and B, but only if he or she gets both.[30] In combinatorial auctions, determining the winning bidder(s) can be a complex process where even the bidder with the highest individual bid is not guaranteed to win.[30] For example, in an auction with four items (W, X, Y and Z), if Bidder A offers $50 for items W & Y, Bidder B offers $30 for items W & X, Bidder C offers $5 for items X & Z and Bidder D offers $30 for items Y & Z, the winners will be Bidders B & D while Bidder A misses out because the combined bids of Bidders B & D is higher ($60) than for Bidders A and C ($55).

Don't get discouraged with your first auction. It takes a good sense of what a vehicle is worth, and the ability to think fast-plus some luck and common sense-to get a good deal. Watch the seasoned bidders at work to catch the gist of it. If you're a smart bidder, government auctions can be a good place to find an inexpensive second car or work truck. Just remember: any deal that seems to be too good to be true probably is!
Several different federal agencies hold government auctions. The General Services Administration is the granddaddy of them all, because it sells on behalf of other departments. When a federal agency no longer needs something — say, a pickup truck — it reports the truck to GSA, which first offers it to other federal agencies and then to state and local governments or nonprofits. If nobody claims the truck, then the GSA auctions it off to the public, and you get your chance at it.
