Retail price in the summary of purchases

[agata81]

Hello

I have a store in Prestashop 1.6.1.2

I am trying to add a retail (basic) price in addition to the group discount and promotion price.

The retail price is 36.90

I managed to split the group price and with an additional promotion

I modified the shopping-cart-product-line.tpl file

Code corresponding to the group rebate (price after a permanent rebate):

<td class="cart_unit" data-title="{l s='Cena po stałym rabacie'}">
        <ul class="price text-right" id="product_price_{$product.id_product}_{$product.id_product_attribute}{if $quantityDisplayed > 0}_nocustom{/if}_{$product.id_address_delivery|intval}{if !empty($product.gift)}_gift{/if}">
            {if !empty($product.gift)}
                <li class="gift-icon">{l s='Gift!'}</li>
            {else}
                {if !$priceDisplay}
                    
                    <li class="old-price-koszyk">{convertPrice price=$product.price_without_specific_price}</li>
                {/if}
            {/if}
        </ul>
    </td>

 

Additional promotion code (price after additional discount):

<td class="cart_unit" data-title="{l s='Cena po dodatkowym rabacie'}">
        <ul class="price text-right" id="product_price_{$product.id_product}_{$product.id_product_attribute}{if $quantityDisplayed > 0}_nocustom{/if}_{$product.id_address_delivery|intval}{if !empty($product.gift)}_gift{/if}">
            {if !empty($product.gift)}
                <li class="gift-icon">{l s='Gift!'}</li>
            {else}
                {if !$priceDisplay}
                    <li class="price{if isset($product.is_discounted) && $product.is_discounted && isset($product.reduction_applies) && $product.reduction_applies} special-price{/if}">{convertPrice price=$product.price_wt}</li>
                {else}
                        <li class="price{if isset($product.is_discounted) && $product.is_discounted && isset($product.reduction_applies) && $product.reduction_applies} special-price{/if}">{convertPrice price=$product.price}</li>
                {/if}
                
            {/if}
        </ul>
    </td>

 

I don't know how to display the retail price, i.e. without any discount.

Please help
