I've purchased this script recently, and so far it's been a pleasant experience!
It's easy to use, requires almost no coding skills(i've had to figure out how to add banner code) and the support is better than the company I was with before. They were helpful with the issuers that I've submitted to them. I would recommend this script to people who are interested in having their own discount/coupon site. You might think that the price is steep, but they constantly have some discount deals on their site. I've got mine for free when I signed up for hosting with avahost.net.
