I've been looking locally myself, but for the nitrogen reservoirs on my coilover shocks. They use a schrader valve just like your tires. Les Schwab did not have nitrogen, but they suggested the Wal-mart tire center. I called them and they were clueless. A local place (also NorCal, but not the Bay Area) called Bob's Tires has nitrogen and will fill each wheel for $7.50. I'd try some of your local tire shops.

Honestly if you're not racing the car, then I think you're wasting your money. I seriously doubt that the tires come filled with nitrogen from the factory. I've never heard this before. However, your dealer may have deflated them and refilled them with nitrogen as a "perk" for the buyer. If you're low on pressure now, fill it with air and then when you find a shop with nitrogen just have them deflate the tire and refill it.

BTW, my solution is to just buy a nitrogen bottle from a welding supply shop. I'm going at lunch today to pick one up. This way I can adjust my shock pressure to my heart's content without paying $7.50 each time. Total cost for the bottle, gauge, regulator, and schrader attachment is going to be about $200 and then ~$15 or so to refill it once a year. I may do my tires too when I start autocrossing the car.
