I used to be a hardcore pay-per-click promoter but the market is really starting to get flooded so the prices are continuing to escalate because of the demand to be on the front page. My gut tells me that your organic traffic will bring you a better ROI over time. I recommend Adwords not so much for retail but more for big ticket sales where you can keep burn through a lot of clicks and still make profit on just one sale. Organic traffic plus building a subscriber list brings the best ROI.
Thanks for the advice! I will keep this in mind. Organic traffic has been the best for me so far.
