A shop in Fetter Lane? (5,5)

I believe the answer is:

chain store

I'm a little stuck... Click here to teach me more about this clue!

'a shop' is the definition.
(chain store is a kind of shop)

'fetter lane?' is the wordplay.
'fetter' becomes 'chain' (I've seen this before).
'lane?' becomes 'store' (I can't explain this - if you can you should believe this answer much more).
'chain'+'store'='CHAIN-STORE'

'in' acts as a link.

Can you help me to learn more?

(Other definitions for chain store that I've seen before include "shop" , "an outlet" , "One of a series of firm's shops" .)
