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.

<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>
