Money can be sure to offer temptations (5)
I believe the answer is:
lures
'temptations' is the definition.
(lure is a kind of temptation)
'money can be sure' is the wordplay.
'money' becomes 'l' (L can mean 'pounds').
'can be' is an anagram indicator.
'sure' with letters rearranged gives 'ures'.
'l'+'ures'='LURES'
'to offer' is the link.
(Other definitions for lures that I've seen before include "Tempts or entices" , "Baits or attractions" , "Draws" , "Baits, decoys" , "Rules with decoys" .)
