Variation Price Filter

Hi,

Has the following filter been removed from WooCommerce woocommerce_product_variation_get_regular_price or woocommerce_product_variation_get_price. I am running the following code:

function _custom_price_varaints( $price, $product ) {

    echo $product->get_title() . " - " . $price;
    die('123');

}

add_filter('woocommerce_product_variation_get_regular_price',  '_custom_price_varaints', 10, 2 );
add_filter('woocommerce_product_variation_get_price', '_custom_price_varaints', 10, 2 );

And it never seems to fire – I need to tweak the price on the catalog view on the front end and it’s not the HTML price I need to change.

Any ideas?
