Avoid signing up at all costs!
We started using this app over a year ago. While the app itself works fine (though with limitations), after using it for about 6 months we ended up finding another app that worked better for us. We deleted the application, and months later they charged us for another year subscription. I tried contacting them the same day as the charge and they refused to refund us, even though we had cancelled our account months ago. I've since had to file a chargeback with our credit card company, while the Coupon Pop app developers have not responded to any more of my emails.

Fantastic when free. Not worth $9.99 a month.
