I am wanting to get my brother, who lives in the US, an iTMS GC for Xmas. However, I am of course using iTMS Canada. My question is, if I buy an iTMS GC off the iTMS Canada site, will he be able to use it on the US site, or will it be for Canada only? I ask because there is difference in the amount of music a person could purchase if a $50 iTMS GC was ordered in CAD vs. USD currency. ($50 CAD != $50 USD although it's closer than it used to be!) So, can I order from iTMS Canada for him, or do I need to log into the US site somehow to do this? Or can I do it without needing to sign it, and just do it from Apple's website? I haven't really looked into things any further, and just wanted to make sure I go about things the proper way. Thanks in advance for any advice!
