<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.
