Pronounced retail angle to be greedy (7)
I believe the answer is:
selfish
'greedy' is the definition.
(greed is selfish)
'pronounced retail angle' is the wordplay.
'pronounced retail' becomes 'sel' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'angle' becomes 'fish' (synonyms).
'sel'+'fish'='SELFISH'
'to be' acts as a link.
(Other definitions for selfish that I've seen before include "without consideration" , "Mercenary" , "inconsiderate" , "Putting own interests first" , "Egotistical" .)
