I don’t know if that’s possible right now. It will probably involve some set-up from the WooCommerce side. Since all the buttons of the Shop page lead to the cart page, including the button in the mini-cart pop-up, we can’t just ignore the existence of such a page and have only a checkout page. Maybe the cart url can be redirected to the checkout page but that needs modifying the .htaccess. I don’t know, all I know is I need a one step shorter buying process. :) The other thing that frustrates me is why we have the delivery radio buttons both in cart and checkout pages.
