Some of my products require the customer to pay after the order has been processed. These are labelled POA (price on application) next to the 'add to cart' buttons. I have made the shortcode price="000.001" which seems to work fine going through checkout with no price attached to it but shows as an error when it reaches PayPal Sandbox.
What can I do to make the orders processed with no price?
The following ERROR appears:
