HRS §490:2A-205
When a merchant's lease offer cannot be withdrawn
A merchant's written offer to lease goods can be made binding for a set time, even without payment, if it says so and is signed. The offer cannot be held open for more than three months. If the form comes from the other side, the merchant must sign the promise separately.
The statute, as written — Firm offers
An offer by a merchant to lease goods to or from another person in a signed record that by its terms gives assurance it will be held open is not revocable, for lack of consideration, during the time stated or, if no time is stated, for a reasonable time, but in no event may the period of irrevocability exceed three months. Any such term of assurance on a form supplied by the offeree must be separately signed by the offeror.
