OWL energy monitor drops to £30

Fancy shaving 15 per cent off your electricity bill? That's how much you could cut off your bill by using an energy monitor, a small gadget that displays your eleccie consumption. Previously the average monitor would've set you back £45, but a new sale this month means you can pick one up -- the OWL -- for a piffling £30.

As Tracey at EcoStreet notes, you can buy the OWL from Ethical Superstore for the discounted price of £30 until 18 August. Before you buy, first make sure you read SmartPlanet's in-depth test of the OWL.
