Smoking Christmas Light Deal
If you live near me and have United Power, they have a smoking deal right now for buying LED Christmas Lights (notice how I said Christmas Lights and not holiday lights!) You can get up to $4 per strand rebated to you, with no limit. So if you buy LED lights on sale (I got a bunch for $7.99 each yesterday at Ace), you can get half the price rebated and then the rest will pay for itself in one season with the 90%-lower power consumption of LED's. That's a nice deal.
For those in other regions, your utility might do the same thing. It's a nice way to switch to the newer technology.
