1 day after release, it's already doubled in price?

I can't seem to find it either on any website. However here in Argentina there doesn't seem to be a stock issue(mainly because almost to nobody has a 3ds) the catch is, the game is like 80 dollars not because of shipment shortages, but because that's always their price.
And thats why I will wait to order mine via ebay or something related. I will not go digital because that box art is sick!
