Web site helps home builders save money on green products

Want a discount on Energy Star-rated products? If you're looking to purchase energy-saving products in bulk, www.QuantityQuotes.net could save you money. How it works: Builders specify Energy Star products they need online, and the Energy Star-sponsored site notifies suppliers of the request. Those suppliers submit bids, and builders get to choose whom they'll buy from, if at all.

Did we mention it's free and anonymous? All you have to do is submit your city and state. It helps if you describe the project, too, and you can leave your name and information if you prefer to be contacted directly.

Big names such as Whirlpool and Sears participate, as well as smaller, specialized outfits. Who knows: your next batch of light bulbs or order of refrigerators could cost less than you expect.
