An order bump is a marketing strategy used by businesses to increase sales by offering customers an additional, complementary product or service at the point of purchase. This upsell technique is often presented as a last-minute, irresistible offer that is directly related to the original purchase and provides added value to the customer. The goal of an order bump is to entice customers to spend more money and increase the overall value of their purchase. This can be a win-win situation for both the business and the customer, as the customer receives a valuable add-on to their purchase and the business generates more revenue.
