Which of the following is not an invitation to treat?

Question

Quizplus · Accepted Answer

The presentation of canned soft drinks in a vending machine is an offer for sale, not an invitation to treat, as the customer is able to immediately accept the offer by inserting money into the machine and receiving the product in return. A call for bids by an auctioneer, an advertisement calling for tenders, and the listing of an item for sale in a supermarket catalogue are all invitations to treat as they are inquiries into potential interest, which may or may not culminate in a legal offer.
