Here's another money-saving tip from Clark. The penny-pinching guru's mom recently moved into a new place and wanted a TV in her den and another in her bedroom. But the building wasn't wired for TV in the den. While Clark is a self-proclaimed techno idiot, his brother Gary is a tech genius. It was Gary who told Clark about a wireless video sender called the X10 that lets you send a video signal from one TV to another. The device cost Clark $40 (though it's now selling for around $50) and installation was a breeze.

With one simple piece of equipment, Clark solved the problem for his mom. But he missed out on the real purpose of the product. Cable and satellite companies charge you for every additional box for the extra TVs in your home. The X10, however, will let you pay for just one box and then bounce the signal to your other screens. You can stop paying extra every month for those additional boxes. There may be other devices like the X10, but Clark found this one was so easy to use -- it even came with a remote. The only drawback is that you must watch the same broadcast on all screens in your home. Thanks again, mom!
