I'm going to reach far back in to past years of the brain. Now I also recall this kinda freebi and seem to think that maybe the company arranged with Nat'l PTA to send a huge box of the freebie stuff to all the Council Presidents, who in turn had all the local unit presidents get their stuff at the council meeting.
Then the local unit presidents distributed it to the families of the schools - some sent it home with the students, others handed it out at the large turnout meetings etc.
A couple of years ago, my preschoolers came home with bags that were sponsored by a company like Proctor and Gamble. ( I think????) There was fabric softener, cleaning wipes and some kind of kiddie crackers. It also came with parental advice booklets. This came as a sealed bag. I'll try to find out and let everybody know.
