Builder is doing some construction work. Needing bricks, he goes to Mason, the local brick maker. Mason typically sells bricks to the public for $1.00 per brick. Typically, such sales are for 500 bricks, at the most. Realizing that this will probably be a much bigger sale, Mason states that he will give Builder a good price for the bricks. The contract states that Builder will buy $2,000 worth of bricks to be delivered to the construction site on or before April 1. Based on other brick purchases he has made in the area, Builder expects that he will receive 4,000 bricks, which is what he needs for the building. On April 1, Mason delivers 3,000 bricks to Builder. Needing to finish the building on schedule, Builder has no choice but to use the bricks as delivered. Builder then tells Mason that he expects to receive another 1,000 bricks for his $2,000. Mason refuses to deliver them. If your first name begins with letters between A - K, inclusive, present the legal argument on behalf of Builder.
