What elements are necessary for an offer to be valid Give two examples of non-offers.?

Two examples of non-offers are advertisements that invite customers to make offers (like a sale flyer) and statements made in jest or negotiation (such as "I'll sell you my car for a million dollars" when not intended seriously).
