American Sand & Gravel, Inc., agreed to sell sand to Clark at a special discount if twenty to twenty-five thousand tons were ordered. The discount price was $9.45 per ton, compared with the normal price of $10.00 per ton.

Two years later, Clark orders, and receives, 1,600 tons of sand from American Sand & Gravel. Clark refuses to pay more than $9.45 per ton. American Sand & Gravel sues for the remaining $0.55 per ton. Decision?
