Don't mean to change your business idea But Consider "Twisting" or Adding a Demographic Co-op Discount Club card system into the Swing of Things...

Where customers get a variety of Discounts from Specialty businesses through a Membership type System...

Which could be Marketed individually to particular Niche groups of People who have similar interests...

Exactly the way the Online world Does it.

Give ideas... businesses and customers Added Value to Peak their interests...

And Maybe Tie in a little of The Millionaire Next Door into the overall concept!
