Freebie Marketing

Freebie marketing, also known as the razor and blades business model, is a business model wherein one item is sold at a low price (or given away for free) in order to increase sales of a complementary good, such as supplies (inkjet printers and ink cartridges, "Swiffers" and cleaning fluid, mobile phones and service contracts) or game consoles (accessories and software). It is distinct from loss leader marketing and free sample marketing, which do not depend on complementarity of products or services.

Though the concept and its proverbial example "Give 'em the razor; sell 'em the blades" are widely credited to King Camp Gillette, the inventor of the disposable safety razor and founder of Gillette Safety Razor Company, in fact Gillette did not originate this model.
