Huw and his Howling Commandos at Brickset are reporting that W.H. Smiths news agents are now stocking Series 2 Collectible Minfigures in the UK.
Packs are kept behind the counter, so you won't be able to use your handy bar code cheat sheet or reader.
I can't speak for the supply of minifigures in the UK, but here in the states we had to strike while the iron was hot (or at least in stock). Run out and grab yours today.
