Vacillate on what to get from butcher's (4,3,6)
I believe the answer is:
chop and change
'vacillate' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for chop and change that I've seen before include "Repeatedly vary one's preference" , "Keep making alterations" , "Seesaw (metaphorically)" , "Vacillate - keep altering plans" , "Blow hot and cold" .)
