Food retailer really for shipment (8)

I believe the answer is:

delivery

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

'for shipment' is the definition.
(I've seen this in another clue)

'food retailer really' is the wordplay.
'food retailer' becomes 'deli' (I can't explain this - if you can you should give a lot more credence to this answer).
'really' becomes 'very' (I've seen this in other clues).
'deli'+'very'='DELIVERY'

Can you help me to learn more?

(Other definitions for delivery that I've seen before include "Shipment" , "Chinaman, perhaps" , "that might take 3-5 days" , "Manner of making speech or bowling a ball" , "Address" .)

I've seen this clue in The Telegraph.
