Knox Myer has a heap if YOTH Primes @$119 and the TF4 voyager 2-pack with OP and Grimlock. Not sure I like the look of them though, it seems Hasbro either use no chrome or too much indiscriminately.
TRU has TF4 wave 2 deluxes and voyager Hound (didn't see any Galvatrons though).
There were a few weeks ago, according to a friend I mine. Maybe give them a call?
