A major manufacturer of advanced electronic game play units agreed with an equally large international retailer on certain terms for the production and distribution of the newest such game units. It was agreed that the manufacturer would provide the retailer with the first 1 million units to the exclusion of all other retailers. The retailer would receive its units for an exclusive product launch week, before any other units would be sold wholesale to other retailers. In turn, the retailer agreed to sell the units at precisely $599.99, this price being ideal, according to the manufacturer's market research. Every purchaser would also receive a T-shirt with the manufacturer's logo and $20 in gift coupons for the retail store. If the business relationship later fell apart, which party could enforce which parts of this agreement? Could it be attacked by others?
