Big Lift Card ($45) gets you half off during the week and 25% off weekends and holidays. If you don't have a car or any hook ups on the mountain, the bus from Homage might be the best deal. It's $59 for the ride and ticket. Emilios and OvRride will do transportation only ($40); Homage does not. Every other bus trip from the city to Hunter with a lift ticket seems to be around $80.
ps- do not be fooled by the snow ads on NYC craigslist
