When overseas customers place an order, the system, by default, adds UK Mainland shipping charges to the invoice, As shipping charges depend on the Country and weight of the parcel, we have to ask customer to pay the shortfall. So I need a 'Payment Link'.
It should be like a form with three boxes..
Customer fills in these boxes according to our email, clicks on 'Add to shopping Cart' and pays the additional shipping as usual.
To get around it, I have temporarily made a 'Pay Link' which you can see on the menu bar on my website [url removed, login to view]
But I need proper shortlink (which connects to my shopping cart) and when customer clicks on 'Add to Cart' button it takes him to payment page. I send this shortlink to customers by email.
