Order bump: add socks for $9 +22% AOV
What this check is
An order bump is a small, relevant extra offered as a checkbox in the cart. Because it is a single tap on a decision already being made, it converts better than any upsell shown later.
How to implement it
Pick a low-cost complementary item with healthy margin, add it as a checkbox with a clear price in the cart page or drawer, and keep it to one offer per cart. Test different pairings over a few hundred carts rather than changing it weekly.
How to verify it
Tick the bump, complete a test order and confirm the item appears as a separate line with its own price, and that removing the tick removes it cleanly.
