How to Manage your Xbox LIVE payment options

Overview

You can choose to use more than one payment method for your Xbox LIVE account. The payment options include credit cards and PayPal accounts. You can use these payment options to buy items from Xbox LIVE Marketplace.

The 2-year Xbox LIVE Gold Contract uses only credit cards as the payment option. The other payment options like Debit Cards, Prepaid cards and PayPal are not valid for this subscription. However, you can change your payment to another credit card.

If it is before the end of the two years and there is no credit card associated with your account, it is assumed you have terminated the subscription, and you will be charged an Early Termination Fee and any applicable taxes.

It is easy to edit your payment options on your console or at Xbox.com

Steps to Follow

Add or change a payment option using your console

1) Use your Xbox LIVE gamertag to Sign in.

2) Proceed to Settings and then select Account.

3) Select Manage Payment Options, and then choose either of the following:

• If you want to add a new credit card, select Add Credit Card.
• If you want to use your PayPal account on Xbox LIVE, select Add PayPal. You will be required to enter your PayPal username and password. Follow the instructions to add PayPal as a payment option. You cannot use PayPal as a payment option for the 2 year Xbox LIVE Gold Contract. PayPal is not available in all regions.

4) After making changes to payment options, select Update Payment Option.

Unable to select MS account as payment option

Sorry for the double post, but when trying to edit, it said permission denied.

Also, the support page chat client hung for a minute or two, said no Ambassador could be found with a prompt to reword my message - but the text box was disabled and I could not reword my message without restarting the chat client. I had already tried
support.xbox.com/.../contact-us, but when clicking "Downloadable Content" to advance to step 2, the page shows a section with the Xbox 360 loading icon, then disappears. JavaScript and
cookies are enabled, else I could not get so far as step 1 on that page or post here.

 

If it's a backwards compatible game, you would need to use a 360 console in order to use your account balance to make the purchase.

 

Maybe you want a Payment option as Back Up cause 8.99 + Tax = more than 10 , so please check the price again

 

Is this game backward compatible for X360?
