Converting MS points into money(US&CA)

[Bizarre]

Ok so I just got my Xbox (add if you like - nickm48) and I was checking out the marketplace and I saw GTA San Andreas for download, I'm pretty sure it was anywhere around 1400-1600 MS points, so what is the equivalent in CA/US money?

800 ms points == about 10 dollars
1600 ms points == about 20 dollars

you can figure the rest out from there
