Best Buy is offering a free figure & power disc pack when you preorder the 2.0 Collector's Edition
Currently it is only available to PS3, but it has been said they are fixing it so it will be with PS4 too.
Also, GotG playset is an option for your free figure!

Also, as Romulus77 has stated, you can get a Toy Box starter pack (for some reason PS4 only) as your free figure when you preorder a normal starter pack.
