If you're going skiing in the Rockies this winter and dont have tickets yet it's definitely worth trying priceline now. I was planning on driving to Crested Butte next February becuase tickets started at $373/ea. Last week I tried priceline to check out how the system works becuase I haven't used them in years. I put in what I thought was a rediculously low bid of just less than half the lowest discounted fare available and was shocked it was accepted. Now I see the promotion advertised on the site (It wasn't there when I bid). They say in the ad up to 50% off but you can go lower still, how far exactly I don't know but my discount was 53%.
