Terms & conditions checkbox
The Sunrise theme provides a checkbox on the cart page to ask your customers to agree to your terms and conditions. All you need to do is create a page named “Terms and conditions” then add your content to it. See Shopify’s docs for more info on creating pages…
Docs – how to create a new page
If you don’t need the agree terms checkbox, you can switch it off. To do that, just click “Customize” next to your theme name and then click the cart icon in the header. Once you see the cart page, you’ll notice a new section appear in the sidebar named “Cart page”. Use the settings in that section and don’t forget to save your changes.
