WooCommerce: Adding a setup fee to certain products

I found a solution using this plugin. It’s very easy. If you want to display the setup fee in your product description, use the following code:

$id = get_the_ID();
$fee_name   = get_post_meta( $id, 'product-fee-name', true );
$fee_amount = get_post_meta( $id, 'product-fee-amount', true );
echo $fee_name . ' - ' . $fee_amount;
