Yes...
About 7 pounds but its better value to get 1200
with a credit card or go to a store and buy a Microsoft points card.
The only way to obtain 1600 Microsoft points is to buy them.
Around $6-7.
No. You earn gamer points playing games, Microsoft points are to buy things on the xbox live market place.
4000 points is the largest you can buy in the US.
If you have an Xbox 360 i believe you can buy it in the Xbox Live Arcade thing that lets you buy games. If its not on sale it's $15, or 1200 Microsoft Points, but if its on sale it just $10, or 600 Microsoft points. If you don't have an Xbox 360 and you want to get it for the computer, check Amazon.com or EAgames.com, and look up Portal in the store.
On your account. I had 600 then my 360 broke got a new one still used my old points.
you have to buy them
You Buy it with Microsoft points
