What country are you located in? What type of credit/debit card are you attempting to use?

In countries where the iTunes Store only sells apps, the accepted payment methods are Visa, MasterCard, and American Express. Other payment types such as gift cards, store credit, monthly allowances, ClickandBuy, and PayPal are not accepted. Depending on your App Store country, prices may be listed in your local currency, US Dollars, or Euros.    http://support.apple.com/kb/HT5552
