Huw and his Howling Commandos at Brickset are reporting that the Series 3 Collectible Minifigures have established a beach head at Argos in the UK. It seems Argos will let you reserve items and pick them up in the store, a nice feature!
Also, if I understand correctly, the box ratios appear to be different in the UK. Instead of only having two Fishermen per case there are now three. The Space Alien count went down to three from four per case as a result.
