Completely agree. I'll often take a look at the "top in-app purchases" as well. "$9.99", ok, but if I see a "$129.99" for a "big crate of gems"...
I just got to question how the developers felt that it was morally acceptable to create a toxic enough app experience that drives users to use in app purchases through deceptive tactics during the first few minutes of play to go and drop +$100 on virtual gems.
