So how do you spend real money, not points with the XBOX 360? Bungie explains!

By now everyone knows that in order to purchase the new maps for Halo 2 you have to go the old school route and actually use regular money, not Microsoft points.  Some people have been trying to figure out how to do this on their 360's since normally transactions are made by points.  Bungie has posted on their website the instructions on how to do this:

Xbox 360 made it possible to buy a Live Account and Marketplace points without a credit card – so we apologize for the following inconvenience if you’re a 360 owner with no credit card attached to your Live account, but thanks to Halo 2’s olde school tech, this is the simplest way to do it:

Account Management

1.  In the Xbox Dashboard, select the profile that you want to modify, and then select Account Management.
2.  Select Memberships.
3.  Select the membership that you want to update.
4.  Select Change Payment Options.
5.  Select Add Credit Card.
6.  Enter the credit card information for the card that you want to add. This can also be a debit or Visa (or similar) gift card, however, some restrictions may apply.
