The document discusses numerous cases related to the formation of contracts, specifically focusing on offer, acceptance, and termination of offers. Regarding offers, cases establish that displaying goods does not constitute an offer, advertisements are generally invitations to treat rather than offers, and bids can be withdrawn before acceptance. Regarding acceptance, cases show that counteroffers reject original offers, silence does not imply acceptance, and conduct can indicate acceptance. Regarding termination, cases demonstrate that offers can be revoked before acceptance.
