I also avoid businesses who have given in to the envircommies. Anytime I notice a business touting some environmental benefit to their products, services, or operations I either call or drop them a note letting them know why I will no longer be a customer.
I dropped Waste Management as my garbage picker upper when they started promoting how "green" they were and I discovered that I was paying for their "greenness" to the tune of $78 quarterly. I switched to a non green company at $50 per quarter and let W-M know why.
