I have around $37 in my account - all converted from when MS stopped their MS Points scheme and converted my leftover MS Points in MS$$$

The MS points were loaded on my account from MS points cards

I've tried buying games or addons for my XB360 from the website but it doesn't give me an option to pay using my account credit and just charges my credit card (tested on a small DLC)

I've tried buying a game from Microsoft's NZ website - Dance Central 3 for the 360 is $23.95 delivered ($99 on XB Live - go figure) but again, no option to pay using my credit


Anybody know how I can use up my microsoft credits?
