Our system for shipping charges is set up to bill for shipping after the order is placed. Once the order is placed, we will bill the order for the shipping cost. We had to set our system up like this, because the shipping module was calculating to much shipping cost for small and light products and not enough for heavy products.
If you placed an order with a credit, debit or any other type of card, we will bill and add the shipping cost to the order, before the order is shipped. If you placed an order through PAYPAL or any other gateways, an invoice for shipping will be sent to you, the invoice will have to be paid before the order is shipped.
