You may wonder why each tier is a single category and why the price differs...
You see, it's all about the time and labor involved in a category. Writing a piece about a painting or artist is not the same as writing a piece about history or mythologies (which requires a lot more research and resources)
That is why, if you do not want a single category but are interested in various things, I created the You're a Epistemophile? tier.
With that being said, I hope you enjoy!
