hmm... I happen to be in Germany right now... maybe something good will come out of this... I'll definitely try to get one of this codes...
Edit: Got it! I'm amazed and at the same time not surprised that Pokémon has a lot more support in Germany than it has in Portugal. Sure, I went to the store right on the first day of the event, but I got the impression it is much more organized (as is Germany in general), there was a lot more advertising of the event and I'm pretty sure here they get a lot more codes than in my country. In Portugal, it's hard to get information on the events and the serial codes run out much faster due to the lower amount.
