er, actually, you do get discount online. Like I said, for those dates you'll get a $28 saving over walking up to the window. Ok it's not huge, but every little helps.
You may get a better deal buying a package, or even buying tickets at supermarkets, but for my trip later this month when I was buying just tickets, the snow.com deal was only $6 dearer than any of those options for 9 days skiing and a lot less hassle.
Good luck with your ticket hunting & have a great trip.
