I found this offer whilst browsing their site. It might not be that great of a deal but if at the end of the year it saves you a £100!!! then it is AMAZING!!

Stickers are subject to availability. so fill in the form quick as they are limited!

If all 100,000 readers of PC Pro shut down their computers down and turned them off at the wall overnight, instead of leaving them on, it would save enough electricity to power around 12,000 homes. And save you or your companies around £4 million a year in the process. So to help you, your colleagues or family remember to power down, PC Pro is once again offering our FREE Switch IT Off stickers.

The stickers can be easily affixed to PCs, monitors, printers or any other peripheral, providing a visual reminder to power down before you head out of the door.

We will provide up to 10 free stickers to each household, and up to 50 stickers to every business, school, college, university or other organisation. Stickers are subject to availability and offered on a first-come, first-served basis.
