Theatrical Supplies Company contracts to sell to Unique Costumes, Inc., seven hundred plastic masks at $1 each to be delivered by October 1. Theatrical knows that Unique will use the masks to make Halloween costumes. Unique usually makes $7,000 profit from the costumes' sale. Theatrical fails to deliver on October 1. Unique attempts to buy substitute masks, but must pay $1.20 for each and take delivery on October 15, cutting Unique's sales in half. Unique sues Theatrical. What is the measure of recovery?
