This add-on allows affiliates to see tracked coupon codes assigned to them in a new Coupons tab in the Affiliate Area. As well as showing the coupon code, the amount of the coupon is also shown to the affiliate.
As of AffiliateWP v2.6, the Coupons tab and shortcode (mentioned below) are included within AffiliateWP itself. If you have v2.6 or newer, you can safely deactivate the Show Affiliate Coupons add-on and retain all functionality.
Note: In order for the Coupons tab to show, the affiliate must have one or more coupons assigned to them.
You can also use the [affiliate_coupons] shortcode to show an affiliate their coupons on any page.
