Hey Guys! So I provide a service that cost $30 and I had great conversions with visitorboost(dot)com, but unfortunately they couldn't provide me with the volume that I needed. So my question is... does anyone know of a good popunder or popup site that has great conversions? I typically try to pay $1 to $4 cpm so that I have a high ROI. Any information would be greatly appreciated considering its hard to find feedback from an advertiser perspective considering all the affiliates out there. Thanks again!!!
