A bonus bundle refers to a collection of additional items or perks that are included with a purchase or subscription, typically offered as an incentive or reward. These bundles often contain exclusive or limited edition products, services, or experiences that enhance the overall value and appeal of the original purchase. Bonus bundles can range from physical items such as free gifts or upgrades, to intangible benefits like access to exclusive content or discounts. They are a popular marketing strategy used by businesses to attract and retain customers, providing them with added value and a sense of appreciation.
