Adding each item's price & weight on Packing Slip

Hi @Amir212

You can try one of them:

{% for item in order.line_items %}
    {% if item.sku != line_item.sku %}
        <span class="line-item-description-line">
            {{ item.final_price | money }}
            {{ item.weight | weight }}
        </span>
    {% endif %}
{% endfor %}

or

{% for item in order.line_items %}
{% if item.sku != prev_sku %}
<tr>
<td>{{ item.final_price | money }}</td>
<td>{{ item.weight }}</td>
</tr>
{% set prev_sku = item.sku %}
{% endif %}
{% endfor %}

I hope it helps @Amir212 !
