You may want to add some text above the checkout button, possibly some legal text or a link to the terms and conditions page.
To create a custom Recurring Orders checkout message, follow these steps:
- From "Shopify Admin", select Apps.
- Select Recurring Orders & Subscriptions by Bold.
- Select Settings.
- Select Display.
- Select the Checkout Page tab.
- Under "Checkout Message", enter the custom text.
- Select Save.
This message will appear right about the "Place my order" button on the recurring checkout page.
