Woocommerce Add to Cart Redirect Nulled adds a field to the Edit Product page (under the General product info) that accepts a URL from the administrator or shop manager. When this field is set, the front-end user (customer) will be redirected to the URL when that product is added to the cart. This can be useful if you want to automatically prompt your customers to purchase other products.
