Used is different from Pre-Owned. See Pre-Owned above. Used means it was used. A box was opened. Wrapping was taken off. Whether it was used for 1 hour, 1 year, or 10 years, it was now Used. The condition of the used item is what matters. The amount of use is what matters. An opened return is used. An unopened return is unused. Both returns are Pre-Owned.
