The site is flooded with spam and bad deals. It used to be such that only truly hot deals were posted, but now many postings are for expired offers, offers with negligible value and self-serving, self-promoting "offers" for those whose sole purpose in posting is to get "badges" of dubious merit.
More recently, the site underwent an "upgrade," and fatwallet's own review pages on the botched upgrade were negative from the start. The fatwallet website editor is still flawed, and complained about often, and has not been fully fixed.
The site owners were in some sort of dispute with their former home state and belligerently left the state for another. They also refuse to discuss how they make money, how they are compensated and how many of their "offers" and deals contain kickbacks. Their rating system used to be fair and subjective, but now they require one to give a reason for a negative review and they are known for banning those who give negative reviews to any offers for any reason -- including common and self-evident ones like not a deal based on price or a bad merchant reputation.
Don't waste you time for a few potential pennies you may get back from a big purchase made through this site --- the site is so poorly managed and operated that you will receive nagging emails from the site itself wanting to know if your pennies ever arrived. It can take many weeks or months to receive anything.
Stick to better sites with objective ratings and you will do much better.
