This plugin makes it VERY EASY to manage 100s of coupons by allowing you to add Categories & Tags to your WooCommerce coupons. Just like you add tags & categories to a post or page or to a WooCommerce product, you can do so even to your WooCommerce coupons.
This plugin will add 2 meta boxes on the Add/Edit Coupon page: one meta box for Tags & another one for Category.
The admin can add multiple tags to a coupon & remove them. It is also possible to assign Category to coupons, including child categories.
The tags & coupons are displayed in 2 columns on the Coupons page. Clicking on a tag or category will filter all the coupons accordingly.
