In order to get your hands on your Azusa figure, all you have to do is leave a comment introducing yourself, which country you are in, what you do and what you like. Something like:-
My name is Mirai Suenaga and I'm located in Japan. I currently attend high school but am conscripted as a Solar Marine. I love Japanese katana *^o~*Thats all you have to do! A ton of folks are signup everyday but dont leave comments - if you want to break out of lurker mode then maybe you have a chance of winning Azunyan for yourself.
If you are not feeling lucky however and want some figures for cheap, then you can get along to ToyLet who are having some Special Deals - heavily discounted figures. The previous auctions they done went so well that they are doing another one where many figures including Nendoroids have auction prices starting at 1 USD.
