Copy and paste this exact code to make your SKU's visible to shoppers on your website. 

This code only works on items that do not have variants. You must have SKU's generated in order for them to appear.  I use the SKUgen APP available in the Shopify App Store to generate SKU's for my products. 


{% if product.selected_or_first_available_variant.sku != blank %}
	<p>SKU: {{ product.selected_or_first_available_variant.sku }}</p>
{% endif %}
