Woo Coupons Pay for Shipping

When coupons amount total is greater than the cart total, woocommerce by default does not allow coupons to pay for the shipping. For example, if cart subtotal is $200 and shipping cost is calculated to $10. Now buyer applies a coupon of total $210 of value. In woocommerce, only $200 coupon amount will count and the buyer still has to pay for his/her shipping. Few shop owners may like to allow coupons to pay for the buyers shipping cost too (if applicable). This plugin will allow shop owners to active that feature.
