Buying US iTunes store movies or music (or even apps in the App Store) is not possible unless you have a US credit card and are resident in the US. If however you still want all the music and the newest movies, iTunes gift cards can help you around this problem.
There are a lot of websites selling these gift cards with any face value from 10$ to 200$ and eBay is also bursting with them.
JerryCards stands out as one of the most secure and easiest services. You buy via PayPal and get the code emailed within seconds. Some websites turn out to be scams or waste time emailing you the code. So JerryCards is a real jewel – especially because they sell Netflix and Xbox gift cards as well!
The main problem with these resellers, including JerryCards, is that they add a hefty percentage (around 15%) to the face value that you purchase. Though I am afraid this is the only way, unless you know someone in the US who can mail you codes all the time.
