Invitation to treat
A sort of preliminary communication at the stage of negotiation, a mere invitation by one party to the other party to make an offer. It is not an offer which is capable of being turned into a contract

Price lists
An auction
An advertisement
the murderer's conviction after she was severely beaten and bruised
The court found out that she was not induced by the offer of the reward but the information was given because she believed that she had not long to live and to ease her conscience
Court's decision
She is entitled to the reward because she was aware the existence of the reward. Her motive is irrelevant.

Supply of information
In Pharmaceutical Society of Great Britain v. Boots Cash Chemists [1953] 1 QB 401, the court ruled that the display of goods on shelf was only an invitation to treat. The proposal was made by the buyer when she placed the item into the basket. There was no sale effected until the customer's offer to buy was accepted by the registered pharmacist at the counter by the acceptance of the price.
In Fisher v. Bell [1961] 1QB 394, CA, the court ruled that the displaying of the flick knife was merely an invitation to treat. Hence, there was no offer for sale and the defendant could not be guilty of an offence.
Offer and counter offer
Modification of the original offer. The acceptor changes a vital term of the contract, such as the price of goods. An acceptance must be absolute and unqualified.
Effect of counter offer
It operates as a rejection of the original offer. The original offer is destroyed and can no longer be accepted. The acceptor becomes the proposer while the proposer now becomes the acceptor.
In Hyde v. Wrench, the plaintiff's letter on 8th of June had rejected the original offer, so there was no acceptance when the plaintiff later wrote to accept the original offer.
Request for further information
It does not operate as a rejection to the original offer as the acceptor is only making a request for further information pertaining to the contract.
In Stevenson Jaques & Co. v. McLean [1880] 5 QBD 346, the court ruled that the plaintiff's telegram was a mere request for further information, not a counter offer, so the defendant's later telegram amounted to a rejection of the original offer.
Cross offer
Both parties are making offers in identical terms. There is no contract between both parties as there are only offers but no acceptance.
