The Shared Disney and Hasbro Exclusive The Vintage Collection 3.75-Inch Rebel Fleet Trooper Troop Builder Set is now in stock at Hasbro Pulse. If you preordered this from them, your order should be processing as well. Price is $41.99 each.
Currently if you are in need this is the only option to get this Set right now, since it sold out at ShopDisney.com when we first reported it being in stock about a week ago.
