In every home solicitation sale in this state, except where a buyer has requested a seller to provide goods or services without delay because of an emergency, the seller shall present to the buyer a written agreement or offer to purchase which designates as the date of the transaction the day on which the buyer has signed it and which contains a statement of the buyer's rights as hereinafter provided for. No such written agreement or offer to purchase shall be effective until after it has been signed by the buyer and he has written the date of such signature in his own handwriting. The statement must appear under the conspicuous caption:"BUYER'S RIGHT TO CANCEL" and read as follows:"If this agreement was solicited at a place other than the seller's business establishment at a fixed location and you decide you do not want these goods or services, you may cancel this agreement by mailing a notice to the seller. The notice must say that you do not want the goods or services and must be mailed before midnight of the third business day after you sign this agreement. The notice must be mailed to: (Name and mailing address of seller)." Until the seller has fully complied with this section, the buyer may cancel the home solicitation sale, by notifying the seller of his intention to cancel in any manner. Any written agreement or offer to purchase which contains the form and content of notice of cancellation required by the federal trade commission and which provides information substantially similar to that required by this section shall be deemed to comply fully with this section.
