Offering free shipping (or delivery as they say in Oz) if the order is over a certain amount is a great way to increase average order amounts. For the Poetry in Flowers cart page we added a little prompt near the checkout button when the customer’s order was below the $55 threshold.

Here is the code:

{% if cart.total_price < 5500 %}
  Note: If you spend {{ 5500 | minus: cart.total_price | money }} more you will qualify for free delivery.
{% endif %}
