Walmart offers two 3-LED Headlamps with Batteries for $2. (You must add two to your cart to get this deal.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's a savings of $4 altogether and a great deal, especially considering that batteries are included. The headbands are adjustable.
You don't need to hire a contractor or do extensive renovations to add value to your home.
