pure bundling

Pure bundling occurs when a consumer can only purchase the entire bundle or nothing, mixed bundling occurs when consumers are offered a choice between the purchasing the entire bundle or one of the separate parts of the bundle.

Pure bundling can be further divided into two cases: in 'joint bundling', the two products are offered together for one bundled price, and, in 'leader bundling', a leader product is offered for discount if purchased with a non-leader product.
