Hi
I managed to get this working using:
function WAEC_WA_Store_Cart_FreeDelivery() {
$totalShipping = 0;
if (true && (($this->InCart("1") == true) && ((isset($_SESSION['eCartCheckoutForm_shipping_postcode'])?substr($_SESSION['eCartCheckoutForm_shipping_postcode'],0,3):"") == "NE3"))) {
$totalShipping += 0;//Result
as I dont really know PHP, I would still appreciate anyones view on a better way to do this or even better if there is a way I can do it using eCart object in Dreamweaver rather than editing the WA_Store_Cart_PHP.php file.
Thanks
Jon
