Oft shaken by the price of confectionery (6)
I believe the answer is:
toffee
'confectionery' is the definition.
(toffee is a kind of confectionery)
'oft shaken by the price' is the wordplay.
'shaken' indicates anagramming the letters.
'by' is a charade indicator (letters next to each other).
'the price' becomes 'fee' (I've seen this before).
'oft' with letters rearranged gives 'tof'.
'tof'+'fee'='TOFFEE'
'of' is the link.
(Other definitions for toffee that I've seen before include "Chewy confection" , "Confectionery made from sugar and butter" , "Caramel" , "Chewy stuff" , "Type of sweet" .)
