Ha ha ha. Oh man. As I mentioned elsewhere, I've never bothered with registering any of my stuff for Club Nintendo. For me, it is as though Club Nintendo doesn't exist. Thus, I don't have to go through the hassle of registering and taking surveys to keep up with different statuses nor do I have to worry, fret or be disappointed about what I would call rather useless prizes. Oh sure, you may have your objections about that but I never seen anything to entice to suddenly become a Club Nintendo member so that's my definition.
Thus, in the choice of getting nothing or something rather useless for free, I choose nothing. I don't have to then convince myself that somehow the reward is worth it or that I should be happy it is free. Nor do I have to be disappointed at the rewards offered. I can just buy my Nintendo products and enjoy them without having to bring in some outside factors to affect my viewpoint of them.
Plus, the reasons something is free is because it is relatively worthless or there is a catch to it. You could say the catch is having to spend hundreds of dollars before hand to get enough points to get a free item or the filling out of surveys and time it takes. Otherwise, most free things in life are of a pretty low quality and unless there is sentimental value, hardly worth keeping or cared about since they are of no cost to you.
