Wow! You said it. I saw those two packs at TRU as well.
I thought "Cool He-man, but why is he supposed to be fighting with Superman? And why does He-man have pink on him? Why does Superman not look to be the same scale? I don't see any other characters so I'll save my thirty bucks."
Had it been just He-man for fifteen bucks I would have grabbed it for sure.
As far as, "How to advertise to people who don't collect toys?" I was not actively collecting toys at the time. I mean I wasn't popping in at stores collecting and searching for variants of any line, but I have two small girls and I could never resist checking out the action figures when I was at the store. Also I popped in at video game stores and comic book stores too. Just cause I stopped collecting toys didn't mean a good MOTU line couldn't draw me right back in.
Most of us share many of the same "nerdy interests" so it's not that hard to figure out where to advertise.
