E-commerce is now making the price of a daily lift ticket cheaper. If you buy the daily ticket online in advance, you can get a better deal. The glitch is, not all ski areas are participating.  Down here in the Sierra, a fair amount of ski areas are giving the lower prices. I checked for the PNW, and it doesn't look like the ski areas are doing it. In Spokane, there are some places that are. I bought a $56 ticket for $32, in the Tahoe area. Liftopia is based out of San Francisco.

They're working on it, though  Washington ski deals    eg, 49N is in.  Lots of blackout dates, though.  Could be ok, when building a road trip..

As differentiated from the Shell Ticket deal,  these guys seem like airline ticket resellers - a sometime in the future thing..  again, ok for planners / travelers, maybe.
