Low Impact Living is holding a contest for greenies. They will be rewarding $500 credit for products and services from their website.

Single family homeowners are eligible to enter. To do so, sign up for a Low Impact Living account and head over the the Environmental Impact Calculator. Deadline is July 15th and winners will be announced on July 28th.

The greenest home receives the $500 credit and a randomly selected runner up will get $250 credit. If you chose a service instead of product, LIL will pay the vendor directly.
