Okay, but do they really pay .2 per click, because I was thinking about joining them since I'm getting low PPC with Google, and their ads seem more clickable (Higher CTR).
As a datafeed consultant, I stay away from pricerunner. They haven't turned good ROI for my clients. So if I pull all my clients out of their site, I doubt they have enough products to justify using them. Besides, my average cpc from them is about 0.36 so how can they afford paying you 0.20? Food for thought
I am not sure how good PriceRunner is. I am going to stick with Adsense. They seem to have good name reconition. Their click rate seems to be very good. So I would suggest stick with what you know works.
