captive product pricing = the pricing of supplies, such as razor blades, staples, computer software, or camera film, which cannot be used without a companion product. Often producers of these products will use a product mix pricing strategy wherein they will set a low price on the companion product with a high mark-up on the supplies

captive finance company = company, usually a wholly owned subsidiary, that exists primarily to finance consumer purchases from the parent company. Prominent examples are General Motors Acceptance Corporation and Ford Motor Credit Company. Although these subsidiaries stand on their own financially, parent companies frequently make subordinated loans to add to their equity positions. This supports the high leverage on which the subsidiaries operate and assures their active participation in the commercial paper and bond markets
