Mate i am in the UK at the moment and every shop is selling Match Attax, Adrenalyn, Crazy Bones England 2010 etc etc. Packets of cards are about 50pence local which is about a dollar back home.
The best sticker/card shop around here sells them for $2.75 a packet but that's for 8 cards.
Stickers are cheaper - $1.50 for a pack of 8!
btw if anyone has any world cup stickers pm me
