Processing of microdata of the products which has reduced price


Two types of prices can be indicated in the Product feed: the regular price of the product and the current reduced price. This information can be identified using Schema.org microdata or Open Graph.
An example of Schema.org markup using the priceSpecification element:
<div itemscope itemtype="http://schema.org/Product">
  <h1 itemprop="name">The Best Product Name</h1>
  <div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
    <strike itemprop="price">1000.00</strike>USD
    <meta itemprop="priceCurrency" content="USD" />
    <span itemprop="priceSpecification" itemscope   
            itemtype="http://schema.org/PriceSpecification">
        <strong itemprop="price">900.00</strong>USD
        <meta itemprop="priceCurrency" content="USD"/>
        (Offer valid until 2029-01-12)
        <meta itemprop="validThrough" content="2029-01-12T00:00:00"/>
    </span>
    </div>
</div>
