Ahh, Memphis beat me to the punch.... You're probably right, Memphis: Serpentor was first offered in stores. And then maybe later, he was offered as a mail-in figure. And don't forget about the Cobra vehicles too! I picked up the HISS and FANG (the tank and the mini-helicopter) back in the day thanks to those mail-ins. Ridiculous tangent: How many points do you think they would've required to get the USS Flagg (if they ever offered it)? And speaking of which: How many points was the ol' Flagg worth?

I don't think Serpentor was ever a mail-in figure. The mail-ins were also a good way to pick up some "older" figures and vehicles that you never bought or missed when they were first in circulation. Both the Joes and the TF's made these type of offers in their later years.
