The message
from "The3rd Earl Of Derby" contains these words:

Two local decorater shops are selling 10 litres johnsons trade matt white
for 13.99GBP and 12.99GBP and the sheds are selling it for 16.99GBP

Gouging, innit. The prices charged by retailers, particularly the sheds
are just plucked from the air according to the perceived value of the
product and nothing to do with the cost.

For example, my nephew works for a shipping firm who deliver for a well
known leather sofa firm. When accidents happen they only pay the
leathershed for the supply cost of the item - rarely more than £50 for a
sofa, often under £30.
