Horace signs a contract to and deliver 40,000 snow globes to Luther by May 11. Horace delivers the snow globes on May 8. On May 12, Luther calls Horace and says the goods are nonconforming because each one had a replica of James Madison inside of it, instead of the figure of John Quincy Adams he had requested. Horace promises to cure within a reasonable time, and on May 17 he delivers 40,000 conforming snow globes to Luther. Has either party breached the contract?
