HasLab's Vintage Collection Jabba's Sail Barge is up to 4230 preorders as of this post. They still need 770 preorders to hit the 5000 preorde goal, but we have 5 more days to go. If this vehicle does get produces it will be one of the rarest Star Wars items produced, so if your on the fence about placing a preorder you may want to make up your mind pretty quick. Once April 3rd hits you are out of luck.
If you would like to place a preorder head on over to Hasbrolab.com.
