Show Affiliate Coupons is a WordPress plugin distributed by AffiliateWP. This add-on allows affiliates to see tracked coupon codes assigned to them in a new “coupons” tab of the affiliate area. As well as showing the coupon code, the amount of the coupon is also shown to the affiliate. It supports integrations for WooCommerce, Easy Digital Downloads, and iThemes Exchange.
Note: In order for the coupons tabs to show, the affiliate must have 1 or more coupons assigned to them. You can also use the [affiliate_coupons] shortcode to show an affiliate their coupons on any page.
