I haven't heard of Peerfly, but I've heard mixed reactions to Clickbank. I use Rakutan and CJ. I might go back and check out Clickbank again. Keep us posted if you try either of these and what your opinion is of them. Would love to hear.

I use Clickbank, and I love them! :)

I am new to WA, we'll am yet to discover

It's been said that clickbank is very trustworthy.

I signed up for clickbank but could not find any affiliates that would work with my niche. I have not heard of the other one. I use Rakutan, Commision Junction, and CJ affiliate
