Talks about a store (6)
I believe the answer is:
orates
'talks' is the definition.
(orating is a kind of talking)
'about a store' is the wordplay.
'about' indicates anagramming the letters.
'a'+'store'='astore'
'astore' is an anagram of 'ORATES'.
(Other definitions for orates that I've seen before include "Speechifies" , "Talks grandly from a platform" , "Makes lengthy or pompous speech" , "Speaks formally, makes speech" , "Talks pompously" .)
