E commerce Deal site Marketing Tips?

Hi all,

I have recently taken over as general manager for a new deal site based in Cardiff, Get My Deal, but marketing deals from the local areas of the customer to national deals. Approaching merchants and getting them on board isnt hard at all, and imagined it to be a lot tougher, though they are now selling at a reduced rate, they get free advertising and is good marketing for them.

the problem now, as I'm sure with other internet based companies is getting the traffic, the end goal making the business a house hold name.

With blog writing, Google PPC campaigns, business listings and forum discussion, is there any Organic marketing that I'm missing out on that really works
