Three places to show upsells that shoppers don’t mind

Under the add-to-cart button

The shopper is already deciding. A related item here gets seen without interrupting them.

In the cart

A small, low-cost add-on just before checkout is an easy yes.

On a landing page

A page built around items that go together lets you show a full set at once.

Where to hold back

Avoid pop-ups that block checkout. Every extra step is another chance to lose the order.

Recommended tool

AOV & Cart Upsells – LiftKit is free on the App Store snapshot used for this site. Keep offers small and optional — never block checkout.
