Oshri Tested Pattern #66: Complementary Upsell
In this checkout experiment, an upgrade offer was added directly above the contact and delivery form. Below the express checkout buttons, the variant showed the item already in the cart (a single bottle priced at $28) and invited shoppers to upgrade to a 3-month supply for only $8 more. The bundle was shown at $36 next to a crossed-out $60, with arrows to browse other upgrade options and a prominent “Upgrade” button. As a result, the standard checkout form was pushed further down the page, behind a second “OR” divider. Imact on completed orders was measured.
