In a contract governed by the Uniform Commercial Code, Rock Quarry agreed to provide Southland Road Constructors with all the rock that Southland needed for the next year, at a price that was 10% below the market price.  Southland agreed, and began receiving rock from Rock.After six months, though, Southland discovered that it could buy rock from another provider at a rate that was 20% below the market price, and it stopped buying from Rock Quarry.  Rock then sued Southland for breach of contract.  Southland countered by pointing out that because there was no stated quantity in the contract, it is unenforceable.
