I have a retail business, and marketing online is great. But is there a forum that deals with physical marketing? (different flyer designs that convert better, different offers, etc.) I know this might deviate from BHW, but... I googled it, and no luck (I guess they suck at SEO?) and what comes up is BHW and WF (both are for online purposes).
You're probably talking about direct response marketing. Google search stuff by Jay Abraham or Dan Kennedy, you'll find their followers around
