Answer 1

For eveeryone that got here from Google. The above is now deprecated as i found out updating to WooCommerce 3.0.1.

Instead of the above you now need to use set_price instead of price

Here is an example:

add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );
function add_custom_price( $cart_object ) {
    $custom_price = 10; // This will be your custome price  
    foreach ( $cart_object->cart_contents as $key => $value ) {
        $value['data']->set_price = $custom_price;
    }
}

I hope this helps people in the future :)
