Hi, we have a game extension for FF and Chrome and are looking for US only installs. To start with, we would be fine with between 2K - 5K installs. I have read about PPI networks such as install monetizer, but we honestly cannot afford $1 - $2 for each US install. We are starting small and need to make some revenues before we can start spending more.So, we are looking for other options. Does anyone here know of cheaper and better alternatives? We are open to all ideas. Thank you.
