Here's a B&#38;M retail idea I thought of recently: "Green Home" a sustainable/organic/green alternative to Home Depot &#38; Lowes.  I think the Whole Foods approach could be applied to the lumbar yard: give DIY homeowners a feel-good alternative at a premium.  The shop would feature lots of bamboo, solar panels, and products from companies like Terracycle (<a href="http://www.terracycle.net/" rel="nofollow">http://www.terracycle.net/</a>).
