Would someone explain to me why 8/4 cost per boardfoot is
almost twice the cost of 4/4 per boardfoot?

The primary legitimate reason for 8/4 costing more than 4/4 is based on
*grading* of the lumber.

It is more difficult to get the same grade when sawing 8/4 as compared to
4/4.

If the lumber is not graded there is minimal justification for a higher
price.
