Complaint Review: Product Programs WWGOA

Received a DVD with a return envelope and a letter indicating: "If you choose to keep the DVD, it's available at the discounted price of only $13.95..."

then it reads: "Because you didn't ask for this special DVD, you don't have to participate or send it back and can consider it a free gift."

The Business Reply Card that comes with it indicates a Yes or No option and the No option reads: "No.  Thanks for the offer, but I'm returning the DVD along with my Reply Form in the enclosed Product Return Enevelope and want no further DVD's at this time."

So....what's the deal?  I'm afraid if I keep the DVD they will bill me $13.95 so I am going through the hassle of returning it per their directions of opening it, putting it with th BRC in the retruns envelope.
