The Crate of Supplies is a Transfer Item acquired by doing Whip's Enhanced Reflexes Village Quest in Phase Two of the Village. You had to recover these crates from crashed transports on Endor, after defeating a handful of Sith Shadhow Thugs and Pirates protecting the ship. The quest could be repeated 6 times. With the removal of the Dathomir Force Sensitive Village, this tradeable item is no longer obtainable unless you buy it from another player. It is nowadays considered as a rare item prized by collectors.
