While I was on holiday in the States a couple of weeks ago I picked up the Snake and Scorpion Aliens from a local Super Target. Had to go back a second time for them though since I couldn't find where they were the first time (I figured they were more likely to be in or near the toy aisles, not the video game and TV section, but clearly I was mistaken
I know it's been mentioned here before, but the difference in price really is crazy. Got both for the equivalent of about £40 when they likely would have been about £70 if I'd gotten them in the UK. You can literally get three figures for the price of two.
Still, the figures themselves look great! The Snake is especially detailed, they definitely did a really great job with these updates.
