add transaction fee on checkout wp ecommerce

I am using WP eCommerce on my WordPress site with The Events Calendar add on to sell tickets to events. All working great but I want to add transaction fee on checkout without adding this total to the ticket price. So say if visitor selects ticket for example Kids entry $4, then I want to add $0.5 to the transaction without adding this to total fee. So once the user checks out then it only applies to the total amount. Is this possible?
