How to add line of text to indicate available discount codes on the checkout page?
I'm looking to add text below the 'discout code' textbox line. I found that editing the 'Subtotal' field in Languages setting will help, but instead the text I enter is replacing the actual 'SUBTOTAL' hrading in the page.
If you want to customize checkout page you can just use app or Shopify plus. Refer https://help.shopify.com/en/manual/checkout-settings/checkout-style
Hope it helps!
