General Mills, the makers of Betty Crocker baking mixes and cereals such as Cheerios, had a contract with the local grocery store, FoodMart, where FoodMart would purchase boxes of cereal and various baking mixes for $1,475. General Mills shipped 35 cartons containing all the boxes of cereal and various baking mixes on September 23. When the manager, John, saw the cartons, he noticed that several of them were damaged. What are John's options concerning the delivery of goods?

General Mills have included language on their Facebook pages and company sites that indicates that if you click on "like," download coupons, or enter a contest sponsored by General Mills, you lose your right to bring suit against the company. In the event of any issues with the product, the coupons, or the contest, you must go to arbitration. Is this type of limitation on pursuit of remedies possible? Is the limitation valid?
