    Joomla: 2.5.18
    Virtuemart: 2.6.10
    AWOCoupon: 2.3.3.1 pro

    I've setup a coupon to offer free shipping and when applying the coupon I get the memory exhausted error. Doing traces I noticed the code is getting into infinite recursion.

    I tracked down the problem to /administrator/components/com_awocoupon/helpers/estore/virtuemart/couponhandler.php and added some of my own code to fix it (My bits have the ZPL comment)

    <?php
            protected function get_storeshipping() {
            if (    version_compare($this->vmversion, '2.9.8', '>=')) {
                    $billtaxrate = $this->getbilltaxrate();
            }
            else {
                    $billtaxrate = 0;

                    $cart_code = $this->vmcart->couponCode;
                if(!empty(    $this->vmcoupon_code)) {
                        $this->vmcart->couponCode = $this->vmcoupon_code;
                }

                if (    version_compare($this->vmversion, '2.0.16', '>=')) 
                {
                        $this->vmcart->couponCode = null; //ZPL
                        $this->vmcart->getCartPrices(); // triggers taxbill tax
                        $this->vmcart->couponCode = $cart_code; //ZPL
                    }
                if(!empty(    $this->vmcoupon_code)) {
                        $this->vmcart->couponCode = $cart_code;
                }

            }
                $obj = (object) array(
                    'shipping_id'=>@$this->vmcart->virtuemart_shipmentmethod_id,
                    'total_notax'=>(float)$this->vmcartPrices['shipmentValue'],
                    'total'=>(float)$this->vmcartPrices['salesPriceShipment'],
            );

            if(!empty(    $billtaxrate)) {
                    $obj->total = $obj->total * (1+$billtaxrate);
            }

            return     $obj;
        }
    ?>


    I don't fully understand what you are trying to accomplish here so I hope the changes are appropriate.

    Hello,

    Your modifications seem fine. Might be getting into an infinite loop when calling getCartPrices. I will run more tests and if it is fine will add it to the core.
    Regards
