which advertisement are offer

Dear Querist,

Generally advertisements are not considered as offers to enter in a binding contract rather they are considered as invitations to offer.

While advertisements usually aren't legal offers, there are three elements that can make an advertisement an offer:

1. The advertisement includes definite terms.

2. The advertisement targets a specific person or a limited group.

3. The circumstances of publication make it clear that the advertiser intended to offer a contract.

For example, if performing an act is all that's needed for acceptance, an advertisement can qualify as an offer. Also, where the advertisement is published (the place) plays an important role to check whether it is an offer or not. 

Regards,

Palak
