In the event that a product has a strikethrough price discount set with a Fan Pass gated discount configured, the product card will initially show the strikethrough price and the newly discounted price.
The product page will then show the same combination even with the Fan Pass connected, the strikethrough price and the newly discounted price. The Fan Pass discount will not be applied at this stage.
Once the product has been added to cart, both cart and checkout will display the product with the strikethrough price and then a new price which is the newly discounted price with the Fan Pass discount applied also.
