In Canada, it's not so much the exchange rate. It's more so that the retailers are just greedy. When the exchange rate was at par Canadians still usually paid anywhere from 10-50% more for the same good. Retailers' justification was that they do not want to constantly change prices based on the exchange rate because it would "confuse consumers." It's a bullshit excuse.
Regardless, this 'heist,' if you can call it one, is ridiculous. Like gpw said, there is no way to move those 6000 copies. Unless it was 6000 limited edition copies, the stolen goods will be worthless in a couple of months once the hype ends.
