Oakland's Blue Sky (formerly known as SR-71) has pretty decent prices for half ounces and ounces. Also, Grass Roots Clinic (SF) usually has pretty good deals. Last week, they had a special of the day, and it was $225/ounce for a strain called Jambalaya. Not sure how much Harborside charges for their high grades, but Divinity Tree (SF) sells their half ounces of high grades for $175.
