A brick supplier wrote to a builder, stating "We will sell you bricks at $1 per brick for as many bricks as you would like to purchase, up to 100,000 per quarter." The brick supplier signed the letter. The builder did not refrain from entering any other deals or otherwise rely on the letter, but he did write back, "I accept your offer to sell any bricks I need to me for $1. We will likely order some bricks this summer." The builder signed the letter. Six months later, the builder placed an order for 50,000 bricks at a $1 per brick. The brick supplier responded that due to transportation costs outside of its control, the price of bricks was now $1.50. The builder sued the supplier for breach of contract. May the builder recover? Question 7 options: a) Yes, because the offer was in writing and signed by the supplier. b) Yes, because the acceptance was in writing and signed by the builder. c) No, because the revocation was based on increased transportation costs. d) No, because the builder did not provide sufficient consideration
