Smart Coupons for WooCommerce

A service fee is added to the checkout of certain products. Currently, when a user checks out, even if the gift card exceeds the order total, he or she still has to pay for the fee with one of the payment gateways. Fees can added like so:
$woocommerce->cart->add_fee( ‘Service Fee’, $service_fee, true, ‘standard’ );

Fix: Before (Line 2176 of ./woocommerce_smart_coupons.php):
$order_total = Smart_Coupons_WC_Compatibility::global_wc()->cart->cart_contents_total + Smart_Coupons_WC_Compatibility::global_wc()->cart->tax_total + Smart_Coupons_WC_Compatibility::global_wc()->cart->shipping_tax_total + Smart_Coupons_WC_Compatibility::global_wc()->cart->shipping_total;

After:
$fees_total = 0;
foreach ( Smart_Coupons_WC_Compatibility::global_wc()->cart->fees as $fee ) {
$fees_total += $fee->amount;
}

$order_total = Smart_Coupons_WC_Compatibility::global_wc()->cart->cart_contents_total + Smart_Coupons_WC_Compatibility::global_wc()->cart->tax_total + Smart_Coupons_WC_Compatibility::global_wc()->cart->shipping_tax_total + Smart_Coupons_WC_Compatibility::global_wc()->cart->shipping_total + $fees_total;
