This is my first post, so apologies if it is in the wrong place or anything like that.
Quality Save (and by default probably Home Bargains too) are selling the mentioned 4" figures. In my local branch (Chorley) I only saw:
Cammy - Street Fighter
Mai Shiranui - King of Fighters
M Bison - Street Fighter
These are from series 1 of the set, so unsure if the other series are available nationwide.
A nice little collectible I guess for the price - £2.97 for 3, whereas the 3 are £5.99 on Amazon.
Sorry for small image . . . if it even works!
