because someone used the googleplay portion, but because it is an older hbo code, the code is still valid in itunes, i tested it myself in itunes, and crashed the program so it would redeem.
they are not suppose too... but this was one of the first codes to introduce googleplay... its possibly sorta like foxredeem has 4 movies which redeem in both uv and itunes but everything newer kills the code once one is used. i was honestly surprised when i tested it and it asked me to download now or later to redeem. verifying the code is working.
