My apologies,
I was under the impression that one was able to check the balance of an iTunes gift card on the apple website; however, a quick google search tells me that's only possible for apple gift cards which I was previously unaware. In that case I'd be happy to trade the .2 BTC for the $100 gift card if someone wishes(no need for it) or otherwise I'll simply close this thread.
Thanks for the information.
