Trash, rubbish, garbage, crap- whatever you throw away, do so. Bury it deep in a landfill or send it off to sea. It's not your problem, you did the right thing taking out your trash. The country isn't in a garbage crisis: At least not yet.
A typical flyer cost 2-10 cents to print; at a small run of 2000 flyers the person sending the flyers in only losing about $400 from pocket. Though to get the true cost of the flyer transportation and disposal cost need be considered. From a consumer perspective, NOTHING annoys me more that a flyer placed on my windshield or in my mail box. I don't want irrelevant junk mail. As a customer, junk mail annoys me- and in receiving junk mail I am less likely to support the company who was trying to get my attention with a silly piece of paper. Of the 4 million tons of junk mail floating around the US it is estimated that only 1 million ton will be recycled.
The brilliance of social networking and marketing is that it allows customers and business to interact on a personal and mutually beneficial platform. Business now have the ability to directly interact with their target market. There is no need for junk mail and flyers. Junk mail is just a waste of primary, secondary, tertiary and capital resources.
