Walmart offers the Woods Electronics 6-Outlet 250-Joule Surge Protector in Gray for $5.59. Choose in-store pickup to avoid the $5.99 shipping fee. (With orders of $25 or more, Amazon charges the same with free shipping.) That's the lowest price we could find by $2. It features a 2-foot power cord, sliding safety covers, and $100,000 connected-equipment warranty.
