Also, depending on the terms of a contract (if one exists), an offer can be withdrawn at any time! Whoever makes an offer can revoke it as long as it hasn't yet been accepted.If the offeree pays the offeror to keep the offer open, any revocation will amount to a breach of that collateral contract. If you change an offer, you revise it, and if you say that you no longer wish to make the offer, you withdraw it. Collins COBUILD Key Words for Finance.
