Answer: The manufacturer, because the shoe store's revocation of its offer was too late.
Step-by-step explanation:
Based on the scenario given in the question, if the store manager subsequently refuses the manufacturer's delivery on December 1, and thee manufacturer sues the shoe store for breach of contract, the manufacturer will prevail because the shoe store's revocation of its offer was too late.
According to the mailbox rule under the contract law, this is the default rule that's used to determine when an offer is considered to be accepted and when there's communication of the acceptance. In this case, the revocation is too late therefore the manufacturer will prevail.
