A person ends short trip in general store (3-4,4)

I believe the answer is:

one-stop shop

'general store' is the definition.

'a person ends short trip' is the wordplay.
'a person' becomes 'one'.
'ends' becomes 'stops' (stopping is a kind of ending).
'short trip' becomes 'hop' (I've seen this before).
'one'+'stops'+'hop'='ONE-STOP SHOP'

'in' acts as a link.

(Another definition for one-stop shop that I've seen is " Seller of all one's needs".)

I've seen this clue in The Times.
