Okay. I will give you a figure, how much we have to pay for import and taxes:
10 units is one actual item.
Each liter fuel costs 5 dollar to import. 10 units of fuel, is 1 liter of fuel. 10 units of goods, is 1 piece.
I am selling fuel for an average of 7.5/8 dollar per liter. That is just about 50 000 - 60 000 $ profit in ((about a week)), with no tax and trucker payment applied and 100 000 $ go for fuel import, for 20000 liter of fuel.
I pay 8000 $ for truckers for 20000 liter fuel. Which means for me, my profit is just 42 000 $ - 52 000 $ for about ((one week)).
Now here comes the tax: 35 %. My profit then becomes the following 27 300 $ - 33 800 $ for about ((one week)).
Now I have to pay for weazel news blips pretty much, to get some customers to my fuel station or my store, otherwise, it will take 1.5x - 2.5x longer to get these figures.
So I have to pay Weazel News Employees about 7 000 - 21 000 $ for a ((week)) GPS blip.
My store takes two times longer to generate money and needs a permanent GPS blip, for being so hidden.
There are import prices for all the goods for the store. I sell goods for about +25 % till +50 % from their import price. Most stores sell for +100 % or even more.
Just an hint: 20 bottles of water pay one delivery for my store, currently that is.
I might increase the payment for each fuel delivery to about 1250 $ next time, but that's about it.
