Look at these shopkeepers (8)
I believe the answer is:
butchers
'look' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
(Other definitions for butchers that I've seen before include "Meat workers" , "Sellers of meat (look!)" , "They prepare and/or sell meat" , "Animal killers in Schubert composition" , "Look (cockney slang) -- Smithfield workers" .)
