The first of the three tick boxes on this page, labelled POA stand for ‘price on application’. Certain items you may want to add might not have a flat charge and need a custom quote, thus this functionality is there.
However, leaving this POA box unticked enables you to fill in the product price, what the consumer is charged, the product margin and the retail price. It’s customisable what a customer would see.
The three tick boxes beneath this make it a little more complicated.
