About March or April last year I bought a game from Italy that got caught in BOTH the canceled flights over the volcano eruption AND the Homeland Security check over the Times Square bombing a month after that. Calling the customs was rather useless because they didn't respond to tracking numbers searches. Over all the package was delayed for almost a month and a half.
Shipping to South America in general is a pain in the ass, no offense.
I usually don't offer shipping there when I sell stuff on ebay, too much bullshit going on over there, especially Brazil.
