Show how close the cart is to free shipping

When to use it

When the announcement bar, cart or footer names a free-shipping threshold, and far more visitors click add-to-cart than reach checkout.

How to run it

1. 1Add a slim progress bar in the cart and on product pages that fills toward the threshold and names the remaining amount as items are added.
2. 2Start with a static threshold line. The live-updating bar is the escalation.

Why it works

Raise the perceived value of acting

A filling bar ("You're $18 away from free shipping") turns the threshold from a checkout surprise into a goal. RIPT Apparel measured +7.9% AOV from a threshold progress bar.
