Starting November 1, 2010, the price of Xbox Live subscriptions increased to the following - $59.99 for 12-Months, $24.99 for 3-Months, and $9.99 for 1-Month.
How much does Xbox Live cost for 1-3 months? For one month, it's $7.99 (There is tax), and for 3 months it's $19.99 I don't know if there's a special pricing for 2 months, but I'm sure it would go by increments of the â¦ one month purchase until you get to 3 months and so on.
