Can you recommend some good "green" sites?

It is hard to go green when so many "green" and recycled products are so expensive. I am familiar with Gaiam and Seventh Generation, but are there any other sites from which to order eco-friendly, "green" products that are somewhat affordable? I have heard of disposable utensils that are like plastic but made from corn or some other biodegradable substance but haven't found a good place to get them. I don't need huge quantities, just enough to stock the breakroom in a small business office. Any leads?
