The promoter or any person offering timeshare interest shall provide a prospective purchaser with a copy of the disclosure document described in RCW 64.36.140 before the execution of any agreement for the purchase of a timeshare. A purchaser may, for seven days following execution of an agreement to purchase a timeshare, cancel the agreement and receive a refund of any consideration paid by providing written notice of the cancellation to the promoter or the promoter's agent either by mail or hand delivery. If the purchaser does not receive the disclosure document, the agreement is voidable by the purchaser until the purchaser receives the document and for seven days thereafter.
