Department of Defense and other agencies will have surplus items. Allowing other agencies to put in requests, and posting of items available online within, and to other USG agencies would allow disposal and reuse of items more readily. Items that are not disposed of that way could be offered for on-line auction, raising money for the USG and savings on the cost of disposal, transport, etc.
If an agency has a surplus, they should be required to provide 10% of the surplus to increase revenues and balance the budget. This should help offset the the agencies that are cost centers and should not be a significant negative impact to the agency with the surplus.
