There is a Fry's in Sac and in Walnut Creek. Also do not forget Electronic's Plus in San Rafael. They have all kinds of stuff. That is where I buy all my shrink wrap tubing and covering material. They have it by the roll, in different colors even. HSC might even have something. I have only tooled around in there for a short time. It is a Salvation store for electronics. Unfortunately we were on a mission that day
