Which type of pricing strategy involves selling a main product at a low price, while additional necessary products are sold at higher prices?

Captive pricing is a strategy where a company sells a primary product, such as a printer or a gaming console, at a low price to attract customers. However, the necessary complementary products or consumables, like ink cartridges or video games, are sold at significantly higher prices. This strategy capitalizes on the dependency created by the main product, ensuring that customers must purchase these additional products to fully utilize their initial investment.

This approach is effective because it generates ongoing revenue from the complementary products, offsetting the lower initial price of the main product and maximizing the overall profitability for the company. It's commonly seen in industries where a core product requires specific branded accessories or consumables, creating a situation where consumers are "captive" to the pricing of those additional items.
