$30 definitely isn't much for a niche book, I would've preferred a short preview or a longer brief.
As an aside, an idea I find underrepresented is gift economies[0]. There's some representation of it in the form of `goodwill` and `relationships`, but this was [likely] a huge part of the economy. Consider the consumption of the average person, and it's going to be more fish and eggs and less MacBooks, and you wouldn't be buying eggs the same way you buy them on the market today[by barter or trade]. You would be definitely using currency for the highly specialized armor, though.
All of this doesn't matter too much in the grand scope, it's perfectly fine to trade 2 shoes for 5 eggs in Skyrim, but some additional depth would be interested if incorporated correctly.
I don’t know how much detail you’re looking for, but it’s a fascinating look at daily life for the lower classes

I especially like this video: https://youtu.be/lZfpQzV2GnM ("Ropes and Hollywood", a rant about the value of rope and the silliness of cutting one 1-4 times every 90 minutes)
