Shopping binges (6)
I believe the answer is:
sprees
'shopping binges' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sprees that I've seen before include "Periods of fun, extravagance or excess" , "Flings indulging impulses, shopping say" , "Brief flings, in the shops, say" , "Brief indulgences of impulses" , "Brief indulgences, flings" .)
