Bait advertising is a tempting but insincere offer to sell a product or service which the advertiser in truth does not intend or want to sell. Its objective is to lead consumers from buying the advertised merchandise, in order to sell something else, usually at a higher price or on a basis more advantageous to the benefit of the advertiser. The primary aim of a bait advertisement is to obtain leads as to persons interested in buying merchandise of the type so advertised.
