Just looked again and noticed this from their inventory sheet available on this auction page, emphasis mine, spelling errors theirs:

$707k = cost of on hand inventory $530k = cost of available inventory

On Hand inventoy means inventory is physically present in a building, regardless of whether it is committed to a customer or not

Available Inventory means on hand inventory that is not committed to a customer

This means they are auctioning off nearly two hundred thousand dollars of product that customers have already paid for.
