Ok, you might not be able to get the Nestle's candy free, but here is a link for $1 off Nestle's candy, 11.5 oz or larger to make the CVS candy $1 each. I was able to print two of the same coupon plus two of the $1 off one bag of Wonka candy, 11.5 oz or larger. (see Magie's post for the CVS deal).
And even better, it doesn't expire until 12/3 so if you want to wait until the after Halloween sales, you could probably get them for free at many places.
You will have to register if you don't belong to the Nestle's site.
