wow, I feel like a dick after having checked out your website.
Cheap lift tickets at the 7 11 in Squamish, but NOT the one on the northbound Sea-To-Sky hwy, only southbound.
Cheap food at Nestors' Market, cheap beer at the liquor store, not cold beer/wine, better coffee at Second Cup then at Starbucks(I guess that's only opinion, but fuck it I know I'm right, there are better independents, check them all out), and if you get drunk at Garfinkels, don't get TOO drunk or they cut you off, and that sucks.
Other than that, get someone with a season pass to buy your food for you when you're at rendezvous or the roundhouse and you'll save some cash by using their discount.
