Gorilla Permits for sale/transfer

Due to a medical emergency, my family and I are unable at this time to use our gorilla trekking permits next month. Our lodge (Nkuringo) has said that we are able to offer them up for resale on the slight chance that someone may want them. The date is May 26th, 2018, for the trek. I have four permits available. Anything over $600 would be an acceptable amount because that is what UWA is able to refund me. I would also like to add that Esther and Lydia at Nkuringo have been extremely helpful in refunding the other portions of our trip.
