The extra effort is in checking that a mistake has not been made.
Assume that you are employed as the oik who puts the shelf tickets on
the shelves. How will you ensure that the till price is the same as
the price shown on the label you have printed out unless you put in
considerable additional effort? How will you ensure that the label is
changed without fail if the till price changes without making a lot of
extra effort?
