As a consumer, I can tell you that whether or not a business is a member has no impact on my purchasing decision. I agree with Ejant: the only time I check is when I think I'm about to be ripped off (e.g., by HVAC, roofing, or plumbing companies) and want to see if they have a bad report. I agree with everybody else: save your hard-earned (but, no doubt, shiny!

) dollars.
