Have you guys ever seen a retailmenot.com type site for WordPress themes, plugins, etc.? I'm finding junk sites that make up fake coupon codes. Is there not a single legitimate, community-powered WP coupon site? I'm thinking there must be but it's buried in junk results on Google and I can't find it. Anyone know?
Why don't you try the themecouponcodes.com, you can check their available coupon codes. It's have many coupon for themes available in that site. Check that out.
Not sure exactly what you are looking for but there is a Groupon plug in for affiliates: http://wordpress.org/extend/plugins/groupon-plugin-for-wordpress/ and Instinct was working on a Groupon type theme: http://getshopped.org/plugins/instincts-newest-beta-release-groupdeals/
It not clear what you want: a coupon site that will work on wordpress or just to find a wordpress site that has coupons on it?
Thanks for asking for clarification. I was trying to find a website that publishes coupons for commercial WordPress themes and plugins (similar to how RetailMeNot publishes coupons for online retailers). The reason I asked was because I was planning to make one and wanted to be sure it hadn't already been done in some supreme way. You can see in my signature that I did end up making one.
