I would like something that functions similarly to http://www.retailmenot.com/ mycoupons.com and fatwallet.com

It can be made from scratch, Joomla, or Wordpress. Im guessing the last two would only need a component/plugin made.

I would like to be able to have the site automatically pull in current coupons, sales and such from my affilaite companies like linkshare, CJ, ShareASale. It also would be useful to be able to manually add them.

Consumer should be able to add coupon codes, comments, register to leave feedback and have their coupon history saved. Over all i would like it to function almost exactly like http://www.retailmenot.com/

Please post any other questions you may have about the project as well as similar sites YOU HAVE MADE ALREADY!
