Writing "paid in full" on a check or money order does make it so even if the document is negotiated. There is a provision under the Uniform Commercial Code for an accord and satisfaction but it requires more than writing "paid in full" in the note section of the document. At this time, you might want to contact the storage facility and see if some arrangements can be made to settle your account before they sell your items.
