We were told a little while ago that it would be on Kapow toys, for our British fans, and here is the link for those who had not seen it yet. These exclusives are priced the same as retail there, and both Hotlink and Megatron are a few pounds off at the moment. They also have Generations Selects Super Megatron for 49.99 pounds.
German action figure site Actionfiguren24 has them available as well, though at a rather hefty premium. Still, it gives an extra option to fans. They have Super Megatron as well, who is at a much smaller markup, when comparing to what he is costing everyone else at the moment. The Netflix figures there are actually shipping out at the moment, as confirmed on this Facebook post.
