I have been using coupon cabin for almost a year now and couldn't be much happier! So, originally, I had a problem with them regulating accounts by IP address. I still do somewhat, but I understand that there needs to be some way to track mis-use of the website and rewards, keeping it fair for all. I use coupon cabin for everything online, and always get cash back checks when they say I will. Very happy, and what a great business they have created!
