Pick and choose after start of sale (6)
I believe the answer is:
select
'pick' is the definition.
(thesaurus)
'choose after start of sale' is the wordplay.
'choose' becomes 'elect' (electing is a kind of choosing).
'after' says to put letters next to each other.
'start of sale' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'elect' after 's' is 'SELECT'.
'and' is the link.
Can you help me to learn more?
(Other definitions for select that I've seen before include "Choose from the elite?" , "Choose from several" , "best" , "Single out" , "Choose, decide" .)
