Can you buy MS points online anywhere?

Hey guys, starting to get really annoyed with the whole MS points thing, since the credit card that is tied to my live account isn't mine, I can't really buy the points with it on the 360, and it's starting to get annoying having to wait a few days for my code to arrive in the post.

Any of you know a web site where you can buy codes with a debit card and then get e-mailed the code instantly? Similar to this web site (http://www.shatteredcrystal.com/), I used to use this site for my EVE Online subscription, you pay for a time code via paypal and then they e-mail you the code as soon as the payment is complete. Was really handy, so I'm looking for something similar to this.

EDIT: Oh yeah, not on eBay though.

you could install the zune's software, since it uses ms points too :p

Ah awesome, I'm guessing it uses .net passport stuff so any point you have in the zune marketplace thing carries over to xbox live and vice versa?

EDIT: God this download/installation is incredibly clunky

EDIT EDIT: Bah can't use it with a UK live account yet :(
