SaaS or on-premise PHP script system with unlimited stores, coupons and deals. Includes social signups, blogging engine, and SEO.
Was able to navigate to the coupon I needed
Pros: Ease of use. Was able to see if the coupon was expired or not and how others had used it. Very helpful.
Cons: There might have been a coupon with more value that expired already. But even with that the coupon I was able to use was useful to me.
