Just-in-time (JIT) is an inventory and production strategy that helps businesses stay streamline and cost-effective without compromising on quality. It ensures that goods are only produced or purchased in the quantity required, and when required, thus avoiding a large quantity of idle products or materials.
Joint demand, also sometimes referred to as derived demand, refers to the relationships between two or more goods or services that are related in some way, such that the demand for one directly affects the demand for the other. For example, when consumer demand for soft drinks increases, the demand for soft drink cans follows suit.

Junk mail, otherwise known as unsolicited mail, is a term used to refer to unwanted promotional materials received through the postal system or email. It is called ‘junk mail’ because it typically contains advertising flyers, brochures, sample products, promotional letters and other offers that are sent out in bulk to a variety of addresses - and many people see it as being less valuable or beneficial than other mail deliveries.
