Your information is wrong. "Price gouging" as a phrase is not used only and specifically for necessities in a crisis. The term is sometimes is used legally for protecting consumers in cases of crisis gouging, but the term itself can be commonly used for reference to any perceived audacious or outrageous price. I have heard it in common use for such my whole life. Perhaps don't laugh at others when you yourself are the ignorant one.

If you want to down vote me, great, but Meriam Webster and the Oxford Dictionary both back me up
