The thank-you page I ignored made $14/order
Trench note: everyone optimizes the order form and leaves the post-purchase page blank. That page is your warmest audience on earth.

Weight-loss offer. Added a one-click upsell on the thank-you page: "Add a 2nd bottle at 40% off — one click, no re-entering card." They just bought 30 seconds ago; trust is peaked.

2 weeks, ~700 buyers:
— 23% took the one-click upsell
— Added ~$14 per original order, blended
— Zero ad cost, zero new friction

The one-click is the trick — no second checkout, no second decision fatigue. Buy momentum is real and it's gone in a minute.

Build the thank-you upsell. Go test it.
