Late post from a spotting a few days back - Target Carousel had the OP and Grimlock Silver Knights two pack, priced at $69.99 IIRC.

AFAIK this is the first time we have seen the FoC Voyager Grimlock mould in retail here... mould is average IMO. FoC colours are allright... this repaint looked good in photos to some extent but actually looks rather lousy in person!!
