gistfile1.txt

{% assign total_saving = 0 %}
{% for item in cart.items %}
{% if item.variant.compare_at_price > item.variant.price %}
{% capture saving %}{{ item.variant.compare_at_price | minus: item.variant.price }}{% endcapture %}
{% assign total_saving = saving | plus: total_saving %}
{% endif %} 
...rest of cart code within for loop
{% endfor %}

Display saving:

Saving - {{ total_saving | money }}

                    Optional, loop through custom product line items if available

                    Line item properties come in as having two parts. The first part will be passed with the default form,
                    but p.last is the actual custom property and may be blank. If it is, don't show it.

                    For more info on line item properties, visit:
