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.
If you buy xbox live from xbox.com via credit card, they continually charge it until you cancel the subscription. I wouldn't trust a greedy corporation like microsoft with my credit card and expect them to not try to take advantage of it. but the prices from buying at a game store are: 1 Month - 7.99. 3 Month - 19.99.
