Jim owns a fishing equipment store. He put an ad in the paper that read "Shokuyu Fishing Rods For Sale, Great Deal, $170." After reading the advertisement,Harry called Jim on the phone and got all the details on the fishing rods. On the phone Jim told Harry the price was $170, but Harry asked Jim if he would take $150. Jim refused. Harry drove over to Jim's store to see the fishing rods. He really wanted one, so he wrote a check for $170 and handed the check to Jim.
