Unless it is expressly specified that an offer to buy or sell goods must be accepted just as made, the offeree may accept an offer and at the same time propose an additional term. This is contrary to general contract law. Under general contract law, the proposed additional term would be considered a counteroffer and the original offered would be rejected. Under Article 2 of the Uniform Commercial Code, the new term does not reject the original offer. A contract arises on the terms of the original offer, and the new term is a counteroffer. The new term does not become binding until accepted by the original offeror.
