On the craft theme. How can I add a promo code box to the shopping cart page?

So that they can apply the promo code on that page before even getting to the checkout page. and the code that they add automatically applies to the checkout page??

Either add an app that provides this functionality (https://apps.shopify.com/search?q=discount%20field%20on%20cart), or else hire a custom coder to rework your cart’s template (https://www.shopify.com/partners/directory/services/store-setup/customize-theme).
