以一個好基本的contract law 去睇,
商家放件貨出來並不是一個offer 係invitation to treat,(除非係offer to the world,太複雜,不在此發表)
由買家去收銀處話要呢件貨一刻先叫offer,跟住商家去acceptance.
如果照 ...
係wor, 我只係記得offer, acceptance...唔記得左invitation to treat
Invitation to Treat
There are situations where it is unclear whether one party is making an
acceptance of an offer or is being asked to make an offer. An invitation to
treat is a negotiating statement and a request for an offer.17 “An invitation to
treat is a mere declaration of willingness to enter into negotiations; it is not
an offer, and cannot be accepted so as to form a binding contract.”18
Thus, customers are invited to offer to buy, and traders keep to
themselves the power to choose whether to accept that offer. Thus, the
traders do not show the necessary intent to give the other party the power
to create a contract. Merely fixing a price does not imply an offer to buy
or to sell. For example, the display of goods by a merchant, price-lists,
circulars and advertisements for goods and services are normally considered
to be invitations to treat.19
