2 York Blues Fest tickets (Sun 30th Sept) ?

I have two tickets for the York Blues festival for sale at the York Duchess, show sarts at 1pm until 10pm and features many top blues artists. Advanced tickets for this event cost 24 or 27 on the door, I am selling for 20 each as I can no longer attend. I can deliver (at certain times in York) or can post them out depending on what ever is easiest. Thanks
