i heard about swaping stars for points, so i checked it out. only to find i didnt have enough stars for the internet browser and there was 200 cards available. then remembered i hadnt registered my metroid prime 3. so i did that (it took about 3 minutes to do). when i got back to the page where i trade my stars for points they were all gone! :-(
anyway i kept checking for the next few days and i think it was the 3rd day they had them :-D.
they gave me a code that i enter on my wii and the points were instantly there for me to use.
my advise is to look every day and soon you shall find some.
i realy hope this helps you out and that you get your points.
take care and happy wii-ing.
