Hi,
To have a simple price and not the full price information, you can potentially edit the view "product / listing_price " and add a div with a specific class, like:
<div class="hikashop_product_simple_price"></div>
And put the simplified value in it, then edit the plugin and replace:
$pattern='/class="hikashop_product_price_main"(.*)class="hikashop_product_price hikashop_product_price_0/msU';
$replacement='class="hikashop_product_price_main" $1 itemprop="price" class="hikashop_product_price hikashop_product_price_0';
$product_page = preg_replace($pattern,$replacement,$product_page,1);
By:
$pattern='/class="hikashop_product_simple_price"(.*)/msU';
$replacement='class="hikashop_product_simple_price" itemprop="price"';
$product_page = preg_replace($pattern,$replacement,$product_page,1);
