Hops off to store (4)
I believe the answer is:
shop
'to store' is the definition.
(synonyms)
'hops off' is the wordplay.
'off' is an anagram indicator.
'hops' is an anagram of 'SHOP'.
(Other definitions for shop that I've seen before include "sales outlet" , "Denounce; boutique" , "Place to buy" , "Sell" , "Establishment for the sale of goods" .)
