OK, let's take those goods out of the warehouse and bring them to the
marketplace. Let's assume that they *initially* have a use-value and an
exchange-value and have been offered for sale. While they are _in the
marketplace_ with price tags on each item, they are not sold "within a
definite period" of time. If these "commodities" physically degrade, they
can "lose" their use-value and capacity to be bearers of exchange-value.
Thus, they *had* value, but no longer *have* value. All of this, in the
above scenario, took place _in the sphere of exchange_. Are those products
-- without use-value or exchange-value -- *now* "commodities"?
