How am I purchasing music with no money?
I have about $0.49 left on my itunes account and I was trying to figure out how to get more itunes money. I thought that if I bought a song over my $0.49 limit, it would give me the option to purchase more itunes money. The song I chose was the regular song price of $1.29, and when I clicked 'purchase' it bought the song for me? But I only had $0.49 left? I don't know how that occurred, but I'm thinking it took money from my debit card account and used that to complete my purchase. Also when I looked onto my debit account it said itunes took $0.80 out of my account. Bottom line is can I purchase itunes money online instead of making unknown purchases, plus I'd really like an explanation for what ENTIRELY just happened. Thank you!
