Reserves a short trip to a place of purchase (8)

I believe the answer is:

bookshop

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

'a place of purchase' is the definition.
I can't judge whether this defines the answer.

'reserves a short trip' is the wordplay.
'reserves' becomes 'books' (booking is a kind of reserving).
'a short trip' becomes 'hop' (I have seen 'Short trip ' mean 'hop' so perhaps 'trip' could also mean 'hop'; 'short' asks for an abbreviation).
'books'+'hop'='BOOKSHOP'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for bookshop that I've seen before include "works store" , "Reading matter sold here" .)

I've seen this clue in the Sydney Morning Herald.
