Im kinda along the thoughts dont knock it until you have tried it.......... not sure. Who knows ey? I dont know the ins and outs really, but if it does/dosent work, learn from it and move on. My book anything is worth a go. I think though it is a short term marketing plan- its not long term , like Helen said earlier its marketing. Short burst of customers to convert. Its a condensed plan, you may have to be cheap, then its what you can pick up along the way - bit of a gateway I suppose for better things. It dosent appear to be a long term strategy
