Which store in Quebec or Toronto can you get an extended battery for the Samsung Galaxy S 2?

I am from Argentina and I cant buy this extended battery for my sgs2 by internet. Someone knows where can I buy in a real store? I can´t find in Bestbuy.
Thanks in advance

Hi there! I found this link and it seems they have stores in Quebec and Toronto. Here's the link to their store locator.

Hope you find one. :)
