I have a digital coupon for a site i promote. I know that there are many coupon feeds such as wp plugins that take coupons from an api of other main sites. My question is: How do i get in one of those api's or feeds in order for lots of sites to pick up my coupon code? I've been looking around and all i seem to find is posts for webmasters to get the feeds onto their sites but not how to get a coupon into those feeds. I would appreciate any info if anyone knows anything. Thanks a lot
