Kmart offers the Bell Automotive Products 3-Outlet Power Strip, model no. 82766311, for $6.49. Plus, Shop Your Way Max members receive free shipping. (Not a member? It's free to sign up for a 90-day trial; otherwise, shipping adds $5.99. In-store pickup is also available.) That's $6 off and the lowest total price we could find for such a 3-outlet strip with a power switch.
