In a Carrotmob, a group of people come together to support a business and in exchange, that business makes an improvement that people care about. In this case, for every $20.00 voucher for products purchased at Ava's Downtown Market, Ava's will devote 15% of the value towards energy efficient lighting improvements. Vouchers are available for purchase now through August 5th, and never expire. You can purchase vouchers here: Web Link
