Answer:
a. Was this a contract for sale?
If this contract had been written and signed by both parties, then it would have been a valid contract for sale. It included the purchase of a specific amount of goods at a specific price.
b. Was this a contract for labor and materials?
No, because it was specific about the price of the windows.
c. Did the contract meet the Uniform Commercial Code requirement of writing?
No it doesn't. UCC requires that all contracts above $500 are written. In the case of merchants that carry out regular operations, they must be able to provide some type of written proof, e.g. an email requesting materials.
d. Is it likely that Houk would win the lawsuit?
No, they will probably lose because they do not have a valid contract.
