Checkout Notice

The Checkout notice is a standalone shopper message that appears in the cart and at checkout when a discount applies — for example “Limited-time offer — don’t miss out!” or “Your bulk-buy saving has been applied.” It’s separate from the per-line Cart Label: the cart label rides on the discount’s cart line item, while the checkout notice is its own banner in the page’s notice area.

Writing the notice

Open a rule and scroll to the Messaging section. Tick Show checkout notice and type the message you want shoppers to see in the Checkout notice field below it.

Plain text only. Unlike the Cart label, the checkout notice does not support message tokens — placeholders such as [percentage_discount] are printed literally, not substituted. Write the finished sentence you want shown.
Leave it blank and the notice falls back to “<label> applied” — your discount’s cart label followed by “applied” (e.g. “Blue Monday – Save 10% applied”). If there’s no label to use, nothing is shown rather than a bare “applied”.

Whether it shows

Whether the notice appears on the storefront is a store-wide choice, not a per-discount one. It’s set in the Applied notice card on the Message Settings tab:

Show for — All discounts (default), Coupon-activated discounts, Automatic discounts only, or None.
Lifetime — Until dismissed — remembered for the session (default) or Once per session.

Where it renders

The notice renders in the notice area of the cart and checkout, on both the classic (shortcode) cart and checkout and the Cart and Checkout blocks. On the block cart and checkout it’s a dismissible banner; once a shopper dismisses it, it stays dismissed for the rest of their browser session, on either surface. It is de-duplicated, so the shopper only ever sees one copy, and on the classic checkout it survives WooCommerce’s AJAX order-review refresh instead of flashing and vanishing.

Previewing it

The admin Cart Preview shows the checkout notice when the Show checkout notice box is ticked: add a qualifying cart and the preview renders the banner text (including the blank-message fallback). Because the preview follows the box rather than the store-wide Show for setting, check that setting too before relying on the preview.
