I noticed that you can get the materials to make hoppers for 20 dollars but you can sell them for over 420. You should Fix this

this isnt a dupe

This is not a dupe - this is due to the fact that you can only sell 10 hoppers a day (which a ton of people do), and tons of people buy hoppers for farms. The shop prices are not fixed, and vary depending on supply and demand - which causes prices to skyrocket.

Yeah the shop is based on supply and demand
