§12A-2-206.
   
   (1) Unless otherwise unambiguously indicated by the language or
   circumstances
   
   (a) an offer to make a contract shall be construed as inviting
   acceptance in any manner and by any medium reasonable in the
   circumstances;
   
   (b) an order or other offer to buy goods for prompt or current
   shipment shall be construed as inviting acceptance either by a prompt
   promise to ship or by the prompt or current shipment of conforming or
   nonconforming goods, but such a shipment of non-conforming goods does
   not constitute an acceptance if the seller seasonably notifies the
   buyer that the shipment is offered only as an accommodation to the
   buyer.
   
   (2) Where the beginning of a requested performance is a reasonable
   mode of acceptance an offeror who is not notified of acceptance within
   a reasonable time may treat the offer as having lapsed before
   acceptance.
