They are a scam. From my experience, they take money from merchants and then do not pass along to their affiliates. One of the oldest confidence games on the Web, if not particularly sophisticated. Or, they are so incompetent that they aren't able to collect from merchants, which is even worse in its own way. They owe me more than $2,000 at the moment. I've left their program as they simply do not pay. Every time you ask where your check is, and when it's coming, you get a different excuse -- the merchant hasn't paid us, there's been a processing delay, your tax form isn't on file (even though it is), etc. They will promise you a processing date and then simply not deliver. They will lie to your face. Do a search for "flexoffers scam" and you'll see others with similar experiences. I am also friends with several large site owners and they have experienced similar issues. Save yourself a headache and use a more reputable affiliate program, such as Commission-Junction or Linkshare. I plan to file suit against them, but I wanted to post here so that no other honest website owners are scammed by them. Also, their site is down a lot and always has "reporting bugs," javascript errors, and unexpected click reporting outages. Totally unprofessional. Do not recommend.
