I tried to share my knowledge about iTunes as I was facing problem to get into USA iTunes store. After a long research I found a way to get enter without any cost. But you will need money if you want to purchase any paid apps or movies from USA iTunes store and the only way to get it via iTunes Gift Card. There are plenty of website out there selling those with a little cost but I prefer http://www.mygiftcardsupply.com/ most because of their quick deliver.
