Kill-A-Watt Electricity Usage Monitor for $17.99 Shipped

Kill-A-Watt Electricity Usage Monitor for $17.99 shipped after code EL20P.  Here is a screenshot for your reference.  Note that it comes in OEM packaging, which means no pretty retail box and marketing materials but is otherwise identical.  Kill-A-Watt is a tool that will help identify power-hungry devices by measuring their actual usage.  It’s simple to use and can easily pay for itself quickly.  We have a couple of them and have found them to be, uh, fun, amusing, and most importantly, very useful.  Here is a review and a video clip about it.
