Not much else to say all points are going to be converted if you have any spare.

I have the beta that has this implemented. It makes much more sense if you want to buy something that isn't 400/800/1600 points so you don't have to buy more points than you actually need. However, Microsoft now puts a tax on every little thing you buy.

I had a feeling it would add tax on the item right now tax is added just to the point you buy.

that sucks tbh, ive got 10k points with nutting to do with them :?(
