HI @TomVufold 

Usually when I have run into this problem, I always check the catalog data to see if I can pull it from there instead of the event data.

By using this in a text field, you can pull in all data on your product to see if the item.price is correct.

{% catalog event.ProductID %}

{{ catalog_item }}

{% endcatalog %}

If this works, I would use this the abandoned cart block depending on what integration your are working in: 

{% catalog item.ProductID %}

{% currency_format catalog_item.metadata|lookup:"price" %}

{% endcatalog %}

If this doesn’t work for you - and you know the tax amount, you can use the django filter below to adjust the shown price:

I hope this helps!
