I bought the pro version of Ultimate WooCommerce Gift Cards. Will I be able to apply discounts on gift cards? For example, sell a GC valued on 39$ for 30$.

Yes, you can offer discounts on the gift card products with our plugin. You can do this by going to the “Discount” tab of our plugin. In this tab, enable the “Enable discount on gift card products” checkbox. Then select the type of discount you want to offer, i.e. 1) Percentage or 2) Fixed Amount. After selecting the discount type, set the price range, and add the discount you want to offer. Save Changes when done and the customers will get the discount on gift cards if they buy them within the set range.
