It didn’t have a name that I knew of, so I started calling it an “order form bump.” It was a small checkbox on the order form after someone filled in their credit card information but before they clicked on the submit button, and that checkbox offered a lower ticket product. It reminded me of the checkout line at the grocery store, where you can add quick impulse purchases like gum, Tic Tacs, and a National Enquirer magazine. The order form bump was the digital version of that.
