Replying to Snowbird Single Day lift ticket for sale

I have 2 4 day tickets for Snowbird with one day left on each. They were a part of a ski and stay package at The Inn. My buddy and I have decided to change our flights and fly out earlier tomorrow so we won't be able to use the tickets. $50 each for the tickets. The tickets are only valid through Monday. My flight is 10am out of SLC so I can meet somewhere early Monday morning to drop the tickets (Little Cottonwood Canyon Parking lot would be good).
