I just bought $150 worth of iTunes cards that the store won't let me use

Question

This is perhaps a common problem -- I don't know. My Bride bought me a 30GB iPod a few years ago. Cayman Islands are disallowed from using the iTunes Store, for whatever the reason. I'm not an angry man, just frustrated. I called a few locations in the U.S., and they assured me that I could purchase an iTunes gift card, redeem it and be on my way to happiness by buying music. I love my iPod, but it needs more than just my owned CDs on it.
I've just spent the past two hours trying to redeem my $150.00 in iTunes gift cards, and I can't get past the menu that requires my credit card number (which I'm more than willing to give) because it's an out-of-U.S. Mastercard. Please help, I'm begging you.
I refuse to use illegal torrents, no matter what the outcome. It's theft. I just want to buy new music -- preferrably hard-driving rock/metal with the dollars I've shelled out. I'm 52 years old. How is an aging rocker to survive without a means to get new music? Tool has a new album I want (new to me). Please help. I'm at my wit's end. Is the Cayman Islands really considered so seditious that we can't participate? I'm a U.S. citizen.
Please help.

Answer 1

Go to the main iTunes store screen.
Go to the very bottom right of thes creen and click flag/marble icon.
Select the US store.
Instead of selecting *Create account*, select Redeem.
Input the card number then select Create new account (unless you already have an iTunes account then use that).
If these iTunes gift cards are from the US, you need to create a US iTunes account with a US address.
