It just shows what you can get with money (4,6)
I believe the answer is:
shop window
'it just shows what you' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'get with money' is the wordplay.
I cannot quite see how this works, but
'get' could be 'win' (winning is a kind of getting) and 'win' is found within the answer.
'with' could be 'w' (abbreviation) and 'w' is found within the answer.
'money' could be 'p' and 'p' is found within the answer.
This explanation may well be incorrect...
'can' is the link.
Can you help me to learn more?
(Another definition for shop window that I've seen is " Where things are shown to advantage".)
