In order to have a valid contract, there must be an offer and acceptance.  The price quote standing alone is not sufficient to constitute a valid offer because essential terms are not stated such as time for delivery, payment, etc.If it had satisfied the requirements of an offer and you knew or should have known of the mistake, you would not be able to take advantage of it.A fundamental principle of contracts is that if a party knew or should have known of a mistake, the party cannot enforce the contract against the other party.  No one is going to sell a new car for $273.
