Store's premier card for hot goods (4)
I believe the answer is:
swag
'hot goods' is the definition.
(thesaurus)
'store's premier card' is the wordplay.
'premier' says to take the initial letters.
'card' becomes 'wag' (both can mean a humorous person).
The first letter of 'stores' is 's'.
's'+'wag'='SWAG'
'for' is the link.
(Other definitions for swag that I've seen before include "Thief's bundle" , "Stolen goods" , "pack of Aussie travellers" , "hot property" , "Loop of drapery" .)
