I've read that I need to return the various books I got yesterday when we rescind which we plan to do. I got worn down and signed yesterday, knowing I can rescind. Glad I got to at least read more into the docs so now I am aware of the minimum we want to buy on resale market. My question is should I just package up the books with the rescind letter and mail it in one shot USPS certified and return receipt to the address listed? Thanks for the advice and help and rescue from an overpriced purchase!
