For a configurable product that has tier prices can the unit price on the product page update to the correct tier price based on the quantity that the user enters.
e.g.
- Buy 100 for £1.55
- Buy 200 for £1.04 each and save 33%
- Buy 300 for £0.78 each and save 50%
- Buy 400 for £0.70 each and save 56%
- Buy 500 for £0.62 each and save 60%
If the user enters 100, the unit price displays as £1.55 correctly. However if the user enters 200, the unit price remains £1.55 whereas it should display £1.04. It does not display the correct tier price until you add the item to the cart.
