An amount of something left over when requirements have been met; an excess of production or supply over demand.
That's not what JSD surplus is. Surplus is an item that is no longer used or doesn't work anymore. In order for it to be taken off of your inventory a Surplus Item Declaration/Transfer form needs to be filled out and processed with your principal and the ED's signature on it. It is then sent to Corie Fuller who makes the decision whether or not to try to sell it on Public Surplus or have Bailey's come to pick it up and dispose of it.
