Shopping place where many get the lot (4)
I believe the answer is:
mall
'shopping place' is the definition.
(I know that mall is a type of shopping center)
'many get the lot' is the wordplay.
'many' becomes 'M' (Roman numeral for a thousand).
'get' is a charade indicator (letters next to each other).
'the lot' becomes 'all' (I've seen this before).
'm'+'all'='MALL'
'where' acts as a link.
(Other definitions for mall that I've seen before include "Shopping area closed to vehicles" , "Shopping facility" , "Glowing material in fire" , "Public walk" , "Traffic-free street" .)
