we did this not a bad deal. Register 3 valid Nintendo products on Nintendo Site here and get their Magazine free for three issues. When trial period id over you can get one year subscription for 12.00.
Valid products are any Nintendo gaming system ( Gameboy, Gameboy Advance, GB Advance SP, Gamecube, DS, Wii, etc ) and most games.
It took a while for the first issue to get here- We first registered in January and got our first issue in April. I am not sure we will sign up for the year but the 3 free issues were great.
