Moacir

This plugin allows you to reduce shipping rate dynamically according to products in the customer cart.
Each product can donate a value to reduce shipping rate, so if there are two products in the cart, one with 2.00 of discount and another with 3.00 of discount, if the shipping rate is 17.00 this plugin will reduce shipping rate to 12.00.
The idea behind this plugin is to improve your sales by transferring the shipping rate to product price avoiding customer to abandon on the checkout/cart page.

<h4>Example: Auto coupon</h4>
Let the customer have a discount of $ 5.00 when the cart reaches $ 50.00.
<ol>
<li>Create a coupon, let’s name it auto_50bucks and enter a short description e.g. $ 50.00 order discount</li>
<li>On the General tab: Select discount type Cart discount, and set the coupon amount to $ 5.00</li>
<li>On the Usage restrictions tab: Set minimum spend to $ 50.00 and check the Auto coupon-box</li>
</ol>
Voila! The discount will be applied when the customer reaches $ 50.00 and a descriptive message will be shown.
If the restrictions are no longer met, it will silently be removed from the cart.
<h4>Example: Apply coupon via an URL</h4>
Apply coupon through an url like this:
<ol>
<li>Use the url www.example.com/url-to-shop?apply_coupon=my_coupon&fill_cart=123</li>
</ol>
Voila! Any coupon can be applied this way. Please note that an empty cart can not contain any coupons. Download the free <a href="https://www.soft79.nl/product/cart-links-for-woocommerce/" rel="nofollow ugc">Cart Links for WooCommerce-plugin</a> to handle the ‘fill_cart’-part of the url.
