I got something about this in the mail today. For $69.95, Nintendo is offering:
Super Mario Sunshine (worth $50)
The Player's Guide (worth $10 or so)
Memory Card 59 (worth $15 or so)
A $10 off coupon for a Wavebird Controller
1-year subscription to Nintendo Power (which is usually $20)
Seeing as I'll need a new memory card for this, and I'll probably buy a Wavebird eventually, it's like getting the subscription and player's guide for free. Just thought I'd pass that along...
