Membership is a hook -- once you have a member, they're more likely to buy from you. It's not really a marketing channel, per se, but it is a method of increasing sales.

"Marketing" gets kind of murky at the edges, really. Consider Pike Place Fish Market in Seattle, who are famous for their fish-throwing, but have never actually spent anything on advertising -- are they marketing or not?
