Opportunity to buy duty-free French perfume, new in, getting it in the box (7,8)

'opportunity to buy duty-free french perfume' is the definition.
I can't judge whether this definition defines the answer.

'new in getting it in the box' is the wordplay.
I cannot really understand how this works, but
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is located in the answer.
'in' is within the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
