1. How do advertisements as invitations to treat differ from advertisements that are considered offers?
Advertisements as invitations to treat invite others to make offers, while offers create immediate legal obligations.
Explanation
Most advertisements are considered invitations to treat, meaning they invite others to make offers rather than constituting offers themselves. They do not create immediate legal obligations unless they contain final, definite terms or are unilateral offers. This distinguishes them from offers, which are clear proposals to be bound upon acceptance.
