Amazon has started to ship out the early preorders for the Black Series 6-Inch Sith Trooper figures which started on September 4th. These early preorders were offered at most major online retailers. My order was just delivered today.
Hasbro stated that there is no difference between these early preordered Sith Troopers (standard packaging) and the ones that will hit retailers on Triple Force Friday on 10/4.
Amazon is "temporally out of stock" on these, but are still taking orders. Just look at "Other Sellers on Amazon" and they are listed there for $19.99.
