OFFER scenario (Carlill v Carbolic Smoke Ball (1893)): Clear advertisement with definite promise = offer. What is the legal result?
Clear advertisement with definite promise = offer; performance = acceptance. An advertisement can be an offer, not just an invitation to treat, if it shows clear intention to be bound. A unilateral contract is accepted by performing the conditions, not by communicating acceptance.

MISTAKE scenario (Raffles v Wichelhaus 1864): A valid contract requires agreement on the same thing on the same sense. What is the legal result?
