Kansas City, Missouri Unclaimed Freight Auctions

Kansas City, Missouri a huge hub for transportation companies in the U.S. Frequently, freight goes unclaimed and despite all efforts by the transportation carrier or moving van lines and storage trucking companies, packages and freight end up at auctions

The same is true for package delivery companies such as UPS, Fedex, Airborne Express and other package delivery companies. In addition, when an insurance claim is made for damaged goods, the damaged merchandise is sold as salvage.
For damaged merchandise, it could be as simple as an item scratched when the packaging was damaged or as extensive as a crushed part of the item casing and everything in between. Many companies took a loss on the shipping cost of a large item and have a policy of not returning the product to the shipper; which would double their shipping costs.

If the item is not claimed the buyer, the freight company ends up with the item. Such is also the case with many types of packages shipped via the United States Postal Service. Those USPS auctions are here.  As far as salvaged goods go, some great deals are to be had in the unclaimed freight auctions.
