Checkout Version Updates (Checkout Extensibility) or Shopify Plus: Script Editor to add Final Sale notifications at checkout for products with tag a “sale” can be added.

You can also write an extension to the checkout interface that runs a function testing if products in shopping cart are tagged with “sale” and then adds an custom note like “Final Sale – Final, No Exchanges or Refunds” beneath those items is a really easy approach. Utterly doable, because you are on Shopify Plus. If not, you may have to hire developer to install the extension in case you have never customized checkout.

Hi! May you share more info on Checkout Extensibility / how to set this up using that method?

For the cart page, you’d need a developer to code that in.

If you want that information on checkout, then you can use Checkout Builder, you can add anything to Checkout if you are on Plus: https://apps.shopify.com/checkout
