Kim and Kanye execute a contract for 500 Travis Scott Air Dior shoes. The contract has all the basic terms, except the parties agree to agree on the price per shoe at a later date. Do Kim and Kanye have a contract? Assuming a contract is present, what would occur if Kim later wants 500 more pairs of shoes? What happens if they fail to agree at all? Are there any mitigating circumstances present if Kim had said, I need at least $500 per set of item, and Kanye conceded? Explain.
