Conditionally Displaying Price & Quantity

You can conditionally display the price and/or quantity for a product by using the logged-in-ness of a customer. An example, from _product.liquid:

{% if site.logged_in? %}
<td class="price">
  {% unless product.buylist_mode? %}
    {% if product.msrp_to_f > variant.sell_price_to_f %}
      <span class="msrp price">{{ product.msrp }}</span>
    {% endif %}
  {% endunless %}
  {{ variant.price }}
</td>
<td class="qty">x {{ variant.qty }}</td>
<td class="buy_button">
  {% if site.may_add_to_cart? %}
    {% if product.preorder? %}
      {{ "Preorder Now" | link_to_add_cart_with_qty: product, variant }}
    {% else %}
      {{ "Buy" | link_to_add_cart_with_qty: product, variant }}
    {% endif %}
  {% endif %}
</td>
{% elsif %}
<td colspan="3">Login to view price and quantity</td>
{% endif %}

The important part being the {% if site.logged_in? %} tag.
