e-Mailing Nintendo does work.
When I got Ocarina of Time 3D (damn, that's over a year ago already), I wanted to register it to get the free soundtrack CD from Club Nintendo. Sadly, some kind of bug prevented me from ordering the CD but it did register my game, so I couldn't try again. Wether or not this bug was something on the Club Nintendo-site, it was too busy at the time or it was something on my end, I don't know.
Anyway, I e-mailed them to say ordering the CD failed, but I really would like to still get it. They replied almost immediately, thanking me for reporting this error and telling me that they would send the CD to anyone who registered their Ocarina of Time 3D copy automatically. I got it the next week.
Since they already decided they would send the CD's regardless, I gather they knew there was some problem for some people. Still, they made me feel like I made a difference!
