How do I implement Rich Snippets on a product/service that has monthly fee?

Question

Using these but it's not validating:

<div itemscope itemtype="http://schema.org/Product">
  <h1 itemprop="name">Product</h1>
  <span itemprop="description">Product
  <div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
    Prices start at <meta itemprop="priceCurrency" content="PHP" />Php
    <span itemprop="price">1799.00 (monthly)
  </div>    
</div>

Answer 1

To represent subscription costs (for an Offer), you could use the UnitPriceSpecification type and its unitCode property.

The unitCode’s value can be a UN/CEFACT Common Code, where MON is the code for month.

In Microdata, this could look like:

<div itemscope itemtype="http://schema.org/Product">

  <div itemprop="offers" itemscope itemtype="http://schema.org/Offer">

    <div itemprop="priceSpecification" itemscope itemtype="http://schema.org/UnitPriceSpecification">
      Prices start at <meta itemprop="priceCurrency" content="PHP" />Php
      <span itemprop="price">1799.00</span>
      <meta itemprop="unitCode" content="MON">(monthly)
    </div>

  </div>
