One way to obtain goods without paying (2,6)

'obtain goods without paying' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'one way' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'way' could be 'n' (Compass direction - North) and 'n' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'to' is the link.

Can you help me to learn more?
