The message
from "Franz Heymann" contains these words:

I found a supplier of a compost based on bracken and horse manure. The
price is almost exactly twice as much as that of ordinary peat based potting
compost. Is this a rip-off?

Much more work required in gathering bracken and mixing/composting.

Sounds very reasonable to me.
