The thing with the site is that you need to redeem a lot of codes to get anything useful. The mario Kart Trophies are mine but each cost 5000 points to get, which works out to 20 unique. I've only managed to pick up 1 from the website itself, the other 5 I own come from ebay.

At the moment though, I am sitting on a stash of 8500 points. The Trophies themselves should be a set of 8, but 2 haven't been released yet. I'm waiting on them being revealed in the run up to Mario Kart 8. There are only 4 games I'm getting between now and the release of Mario Kart 8 so I'll be short a few points if they come back up again for 5000 points, so I'm torn between getting some other cheap games to get the points, or hitting up ebay for someone whom is selling codes.
