(a) In addition to any right otherwise to revoke an offer, the buyer has the right to cancel a home solicitation sale until midnight of the third business day after the day on which the buyer signs an agreement or offer to purchase. Cancellation is evidenced by the buyer giving written notice of cancellation to the seller at the address stated in the agreement or offer to purchase. The buyer may deliver the notice by mail, telegram, manual delivery, or other personal delivery. Written notice of cancellation shall be effective upon the date of postmarking. Telegram delivery is effective when the telegram is ordered. Manual delivery or other personal delivery is effective when delivered to the seller or to the seller's address, whichever comes first. Notice of cancellation need not take a particular form and is sufficient if it indicates, by any form of written expression, the intention of the buyer not to be bound by the home solicitation sale. Notice of buyer's right to cancel must appear on all notes or other evidence of indebtedness given pursuant to any home solicitation sale.
(b) Where a home solicitation sale requires a seller to provide services, he shall not commence performance of such services during the time in which the buyer may cancel.
