There is no general three-day right to cancel a sale in Massachusetts.
There are certain limited situations in which a consumer has a right to cancel a contract and receive a refund for the return of the purchased item. The Attorney General's Regulations and the Federal Trade Commission's Cooling-Off Rule for door-to-door sales apply to sales of certain goods. Door-to-door sales are sales made away from the usual business place of the merchant (the main office or branch office); however, the rule does not apply to sales made entirely over the telephone or by mail.
At the time you agree to the door-to-door sale, you must be given notice of the right to cancel, two copies of the cancellation form, and a copy of your contract or receipt. The contract or receipt must be in writing, and list the name and address of the seller, the date of sale, an explanation of your right to cancel, and how you may assert that right.
To cancel, you must notify the seller in writing at the address given in the contract, by regular mail posted, by telegram sent, or by delivery, no later than midnight of the third business day following the signing of the contract. A business day under this law includes any calendar day except Sunday or holidays. Within 10 days of receiving your cancellation notice, the seller must return your payment. You must allow the seller to pick up the goods at your address, or if the seller requests, and you agree, you may ship them back at the seller's expense and risk. If the seller does not pick up the goods within 20 days of the date of the notice of cancellation, they are yours to do with as you wish.
The FTC's three-day cooling-off period applies to sales of goods priced at $25 or more. It does not apply to sales of real estate, insurance, securities, or emergency home repairs. In Massachusetts, there are similar three-day rights for door-to-door sales. There are also statutes providing a three-day right to rescind for second mortgages, timeshares, health club contracts, and home improvement contracts.
