Assume that Dependable Truck Line has a location in Strike's town and would pick up the shirts at Strike's factory. Assume also that Strike regularly uses Dependable Truck Line and gets a significant discount. The use of Yellow Express Truck Line will require Strike to deliver the shirts to a town 150 miles away (because Yellow Express won't pick up that far from its location) and will cost Strike an additional $600 in shipping costs. Strike did not contact Bailey about the change, but considered it a proposal which he could ignore. He shipped using Dependable Truck Lines.
