The final price no longer works. Shopify changed something and I have not figured it out yet.
Here is the final code in my packing slip. Parts that don’t work now are in red. Starting at line 123 of the unmodified packing slip template:
{%- comment -%} ********adding prices to packing slip *********{%- endcomment -%}
{% assign final_price = nil %}
{% for item in order.line_items %}
{% if item.sku == line_item.sku %}
{% assign final_price = item.final_price %}
{% endif %}
{% endfor %}
{% if final_price %}
{{ final_price | money }}
{% endif %}
{%- comment -%} ********done adding prices to packing slip *********{%- endcomment -%}
The final line number should be 135.
If things don’t format right, I’m afraid I can be no more help. The original solution came from BrianAtWork, as you see from the second entry in the thread - ask him nicely and he will probably help you.
