Costs to Consider: If you're new to Xbox and are excited to sign up for your Xbox Live Gold subscription, there are a few things you should know. Here are some Xbox cost factors to consider: Xbox Live subscriptions are $59.99 for 12 months, $24.99 for three months, and $9.99 for one month.
You can purchase xbox live gold through your xbox if you have signed up for xbox live silver (free). there are 30 day, 3 month, and 1 year options. I pay by the microsoft cards found in any gaming store. The prices are around there for going to the store. If you buy on your xbox it just keeps taking it out of your credit card untill you stop it. 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.
