Enable Live Shipping Rates at Customer Checkout - BigCommerce
ShipBlink allows you to charge your customers the exact live shipping fee — while the Customer is placing the order at the checkout page. This allows you to keep complete transparency with your customers when it comes to shipping rates.
Customers now have the options to choose whether to pay higher for faster shipping or lower for normal shipping. You may also charge an additional fee (flat or percentage-based)
You can set up a rule-based additional fee from the BigCommerce console itself
Mention your fallback shipping rates, fallback package dimensions and additional package weight options for a smooth customer experience at all times on the Checkout Settings page
