Try Ebay, you can somtimes find some good deals there. Remember that
any to the 4pass tickets can only be used one per day.

Right now, Shell is advertising buy $10 worth of gas and get a coupon
for a free lift ticket with purchase of a full price adult lift ticket.
That should still be going during early February. If you need to buy
gas in Denver, it could be a good deal.
