Criticises prices (5)
I believe the answer is:
rates
I believe this is a double definition.
'criticises' is the first definition.
'prices' is the second definition.
(I've seen this before)
(Other definitions for rates that I've seen before include "Former local taxation system" , "(Old) property taxes" , "council tax" , "Fixed prices" , "Tax paid by businesses to a local authority" .)
