I don't dumpster dive...but I have no problem with people who do. They are keeping perfectly good items from the landfills. I do buy used clothes and books but shy away from used shoes and undergarments. My house decorated with a mix of new and used. We live the way we want to and could care less if others look down on it as we are debt free and now, officially, financially independent.
