Blu-Tack where to Buy?


Anyone know if Blu-Tack is available at the bigger Office Depot type places?? I live near San Francisco.

There is also a product called Museum Wax, for securing knick-knacks in earthquake-prone regions like CA. About 6 bucks for a half-pound jar!
thanks all, i picked up some "tac n stik" for $1.29. Its blue and it isn't tearing off the rosewood veneer of my speakers!
Doug: I never picked up the real deal to compare (though I am comparing a piece of plastic laboratory tubing), coiled flat, to Vibrapods (under my tube amp) as we speak. One thing that you DO NOT want to try under speakers is florist's clay.
