Brother Rick,
This is a great idea, and I want to let you know that my company is doing its part. Every year in mid to late October, we always have a sale on the necessary ingredients for making brownies and chocolate chip cookies.
You can even buy them with food stamps
What we've discovered though is that many people just don't want to be bothered baking. Besides, you can't be sure how many of the little brats will come to your door, so you're liable to make too few or too many cookies. Too few would be disappointing, and too many leaves you with the problem of how to get rid of them. I had that problem last year, so I donated my extras to a homeless shelter.
Anyway, this year we're introducing a new product. No need to bake - just give each kid one of these and tell them to share with their friends:
Another great product from Uranus
Don't worry about buying too many - you can return the extras to Wal-Mart for a refund. Or else save them for next year - we've added so much preservative to our food products that you could pass these chocolate bars on to your grandchildren.
