An extended warranty is an optional extra that allows you to extend the initial coverage offered free of charge when you purchase a product, or to broaden the terms of that warranty. Specialized companies often handle the provision of these extended warranty services to retailers, who then sell them for a commission. This represents a significant profit opportunity for distributors, who often incentivize in-store sales staff to promote these extensions by offering them incentives. For example, on Amazon, you might encounter a dynamic offer for extended warranties in the form of a pop-up. Similarly, extended warranty service offers specifically for resellers may be prominently displayed.
