Hi Vinz__I
FYI, our purchase price is not being stored in any post meta. We use custom tables to store all the ATUM data.
You can access all the ATUM props using this method to get the product object:
$atum_product = \Atum\Inc\Helpers::get_atum_product( $product_id );
And then, you can use any of the available getter methods to obtain any ATUM prop. For example:
$purchase_price = $atum_product->get_purchase_price();
I hope this helps.
Best Regards,
Salva.
