Bargain hunter's mecca (4,6)
I believe the answer is:
flea market
'bargain hunter's mecca' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for flea market that I've seen before include "trading opportunity" , "second-hand sale" , "Where second-hand sellers are" , "stalls on the street" , "Seller of second-hand goods" .)
