As i am working on woocommerce for different clients, i come to know about some missing features of Woocommerce regarding the coupons section. So I spent some extra time to code for a plugin which can generate coupons for less sold products i.e. if red colour is high in stock but black is almost out of stock so the store admin can generate the coupon for red colour only. this feature was missing in woocommerce.
Less sold products with special attributes can be sold easily using this feature without effecting sale for popular products. Woocommerce coupon section extention for adding coupon for special attributes.
After enabling this plugin you will see new multiple select box in coupon “user restriction” section. All the other preferences will not be effected, it will work perfectly as it was before.
