WVC 46 - 2 - 205
§46-2-205. Firm offers.
An offer by a merchant to buy or sell goods in a signed
writing which by its terms gives assurance that 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 such period of irrevocability exceed three months; but
any such term of assurance on a form supplied by the offeree must
be separately signed by the offeror.
