bundling is a practice in sales that refers to packaging more than one item together, to induce customes to purchase a main product.

Mixed bundling is when a company offers more than 1 product at 1 price. An example would be a body wash that comes with a cleansing face wash.

The condition imposed by a seller which obliges a buyer to agree to purchase an additional product (tied product) if they wish to purchase their desired product (tying product).

Product bundle pricing is sellers combine several products at the same price. E.g software, books, CDs.

Mixed bundling is preferable to pure bundling when:

- Demands are somewhat negatively correlated.

- Marginal production costs are significant.
