Scroll down to the bottom and make sure it shows all your past purchases as already owned. That way you don't have to re-purchase anything. FGC licenses are 50% off during the sale, but they shouldn't charge you anything for those. FGU licenses are 20% off and you will need the FGU Standard plus FGU Ultimate license DLC. The total package should be 40% off from the bundle.
