If you wind up being one of the first to own an all-electric vehicle, Half Price Books wants your business. While you’re inside browsing the store, your car can be outside getting its fill of free electricity from Green Mountain Energy. The DMN reports that Half Price spent about $10,000 setting up the charging station at its flagship 5803 E. Northwest Highway store and will allow free fill-ups through September 2011, when the program will be re-evaluated.
