 * The button should have a data-coupon-pos attribute providing the coupon position in the cart coupons array.
 * @param event
 */
function removeCoupon(event) {
    var button = event.target;
    var position = parseInt(button.getAttribute('data-coupon-pos'));

    if (uc.cart && uc.cart.coupons && uc.cart.coupons.length > position) {
        uc.cart.coupons.splice(position, 1);
        uc.saveCart();
    }
}
