I received the free month of xbox live. When I go to subscriptions it's set to renew monthly. I turned off the automatic renewal as it's much cheaper to pay for a year in advance. However, there's no option to change from monthly to yearly. If I turn automatic back to 'on' it only gives me the monthly option. I even saw they're having a deal for 12 months for $3.99/month instead of $5.99/month but it won't give me an option to select either yearly offer. My payment option is saved. How can I pay for a year in advance??
