DealExtreme has this 10 pack of LED Keychain flashlights for a total of $4.73 shipped (batteries included). That works out to a $ .47 per keychain light cost, making them perfect stocking stuffers or kid birthday party favors. You can even use these as zipper pulls on your coat so you’ll never be without a working light. I’m not quite certain how they ship these for free when the price is low to begin with. Take advantage while the deal’s available! There’s even a YouTube demo video (1:32) for those who are skeptical.
