Hope to find a bespoke store with constant stock (6,2)
I believe the answer is:
aspire to
'hope' is the definition.
(thesaurus)
'a bespoke store with constant stock' is the wordplay.
'bespoke' is an anagram indicator (I've seen this in other clues).
'with' means one lot of letters go next to another.
'constant' becomes 'pi' (mathematics: 3.14).
'stock' means one lot of letters goes inside another (stock' can mean 'fill').
'store' with letters rearranged gives '[store]'.
'a'+'[store]'='a[store]'
'asreto' placed around 'pi' is 'ASPIRE TO'.
'to find' is the link.
(Other definitions for aspire to that I've seen before include "Aim at - desire greatly" , "Have ambition for, say, 3 Down" .)
