I want the developer to enable a particular shipping method in my Shopify website only when the order amount is greater than a particular amount. And, if that particular shipping method is chosen, then the payment method page should be skipped and the user should be directly sent to the order confirmation page. Basically, I want this for implementing 'Cash On Delivery' feature. I will add one shipping method called 'COD'. I want to enable the COD method when the order amount is atleast INR 500. And, If COD is chosen as the shipping method, then the user should skip the online payment method page.
