It depends on what exactly you are looking for. I don't know of many places in the city that are cheap (I have found some good deals at Lombaridi's on Polk, but not cheap), but if you have a car or can borrow one go to Tri-City at 40900 Grimmer Blvd in Fremont. There I have found some of the best deals on all types of new gear; clothing, skis and snowboards. The later you go in the season, the cheaper things get (of course).\n\nIf you do not mind buying used or surplus gear, try the Wilderness Exchange in Berkeley (1407 San Pablo Ave), the store is great. I have found some good deals there on winter clothing and camping gear.
