The CPA applies when a supplier promotes (advertises) or supplies (for example sells or rents) goods or services in the ordinary course of business to a consumer where consideration (for example money) is given by the consumer to the supplier.
For example: John buys a second hand motor vehicle from a car dealership for R10 000. John is the consumer and the car dealership is the supplier. Both parties are bound to the CPA as:
John is the consumer (he is an individual who receives the motor vehicle).
The car dealership is the supplier (the dealership sells John the motor vehicle).
The transaction is undertaken in the ordinary course of business (the car dealership, everyday, sells motor vehicles to consumers as its business).
Consideration is given for the transaction (John pays R10 000 for the motor vehicle to the car dealership).
