Purses out, rushed to find shop (10)
I believe the answer is:
superstore
'shop' is the definition.
(I know that superstore is a type of supermarket)
'purses out rushed' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'rushed' becomes 'tore' (to tear around is to rush or run fast).
'purses' is an anagram of 'supers'.
'supers'+'tore'='SUPERSTORE'
'to find' is the link.
(Other definitions for superstore that I've seen before include "Large out-of-town shop" , "Retailer" .)
