Есть следующий код:

{if $product.show_price}
  <div class="product-prices">
    

    {block name='product_price'}
      <div
        class="product-price h5 {if $product.has_discount}has-discount{/if}"
        itemprop="offers"
        itemscope
        itemtype="https://schema.org/Offer"
      >
        <link itemprop="availability" href="{$product.seo_availability}"/>
        <meta itemprop="priceCurrency" content="{$currency.iso_code}">

        <div class="current-price">
          <span itemprop="price" content="{$product.price_amount}">{$product.price}</span>

          {if $product.has_discount}
            {if $product.discount_type === 'percentage'}
              <span class="discount discount-percentage">{l s='Save %percentage%' d='Shop.Theme.Catalog' sprintf=['%percentage%' => $product.discount_percentage_absolute]}</span>
            {else}
              <span class="discount discount-amount">
                  {l s='Save %amount%' d='Shop.Theme.Catalog' sprintf=['%amount%' => $product.discount_to_display]}
              </span>
            {/if}
          {/if}
        </div>
      </div>
    {/block}
    {block name='product_discount'}
      {if $product.has_discount}
        <div class="product-discount">

          <span class="regular-price">{$product.regular_price}</span>

    {block name='product_ecotax'}

      {if $product.additional_delivery_times == 1}
        {if $product.delivery_information}
          <span class="delivery-information">{$product.delivery_information}</span>

Он отображает цену, как прописать формулу которая позволит выводить рядом цену с скидкой, к примеру
Розница - 1000 руб.
Мелкий опт. - 930 руб. (-7%)
Опт. - 900 руб. (-10%)
