Atheist's Soul: $504

The market has spoken, the current price for one Atheist's Soul: $504.

The church historically demands a tithe for maintaining the souls it owns for their users. Now the national average income for a couple is roughly £15000 (I got this going backwards from the current poverty threshold).

A tithe is 10% of your income or £750 each for this average couple. So when a church gains your soul they stand to gain £250 in the first year from the maintenance charges less the purchase price and £750 every year after. No wonder everybody seems to be after them!
