4. Price. The price refers to what the target audience needs to give up, but also what they can gain from the behaviour. The audience should be given information about the costs (both monetary and non-monetary) of the current and any alternative behaviour. For example antismoking campaigns focus on the cost of smoking which are not just monetary (the cost of a box of cigarettes) but health (87% of lung cancer deaths linked to smoking). If benefits outweigh costs then the person is likely to adopt the new behaviour. This can also include adding incentives to help guide the behaviour , for example deposits on products, charge for the use of plastic bags and special lanes on roads for cars with more than 2 people inside .
