I know people collect them outside of the USA - but unfortunately because the company is based out of Seattle; the US gets most of the convention and store exclusives and Australia has to hope popcultcha gets them and UK has to hope forbidden planet gets them. It's insane though because you can buy one of these for $8 and have it be worth $50 a week later. This is a great thing to collect as they only really ever appreciate in value if you get the exclusive ones; commons all bets are off.
Here is the highlight of my collection right now:
It was discontinued shortly after reaching stores due to a licensing issue. Paid $12 and it's currently going for upwards of $200 on ebay.
