An order bump is an additional offer for a complimentary product on the checkout page.

The users can accept it with a single click and add it to their order.

WooFunnels allows you to set up order bumps on your checkout page. You can customize the bump skin, sell variable and subscription-based products through it, and much more.

You can even set up multiple order bumps on a single checkout page, allowing users to add one of the many to your order.
