Post, as usual (8)
I believe the answer is:
standard
I believe this clue is a double definition.
'post' is the first definition.
(thesaurus)
'usual' is the second definition.
('standard' can be a synonym of 'usual')
'as' acts as a link.
(Other definitions for standard that I've seen before include "possibly rose" , "Conventional" , "Flag - norm" , "Established model - flag" , "The usual range" .)
