Example: Auto coupon

Let the customer have a discount of $ 5.00 when the cart reaches $ 50.00.

1. Create a coupon, let’s name it auto_50bucks and enter a short description e.g. $ 50.00 order discount
2. On the General tab: Select discount type Cart discount, and set the coupon amount to $ 5.00
3. On the Usage restrictions tab: Set minimum spend to $ 50.00 and check the Auto coupon-box

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.

Example: Apply coupon via an URL

Apply coupon through an url like this:

1. Use the url www.example.com/url-to-shop?apply_coupon=my_coupon&fill_cart=123

Voila! Any coupon can be applied this way. Please note that an empty cart can not contain any coupons. Download the free Cart Links for WooCommerce-plugin to handle the ‘fill_cart’-part of the url.

This plugin has been tested in combination with WP-Multilang.

1. Upload the plugin in the /wp-content/plugins/ directory, or automatically install it through the ‘New Plugin’ menu in WordPress
2. Activate the plugin through the ‘Plugins’ menu in WordPress
