I have one single product I sell. This product has its own page including image and a buy now button added via a shortcode. This directly takes you to the cart page.
I want to remove the continue shopping button from the cart page as it does not make sense with just one single product.
This question has been answered before by using CSS but I would like to use a hook (action/filter) solution, that I can add to my functions.php.
The customer never gets to see the shop and single product page as this will only add confusion. The links to these pages, via the thumbnail and product name in the cart, will be removed as well.)
