Visited my local store and found them alongside the Disney infinity figures hidden behind the Marvel toy box game discs.
I'm a mite annoyed its not advertised online unless its Smyth's or Amazon, not sure why they aren't advertising they've been released when they apparently did for outside the UK.
^ You need to keep checking the Disney Infinity Museum, you'll be surprised how much merchandise there is, I'm updating now and will have more coming in every week
