They sell booze and repackaged TV dinners (unopened) (8)

I believe the answer is:

vintners

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

'they sell booze' is the definition.
The definition suggests an adverb but the answer is not.

'repackaged tv dinners unopened' is the wordplay.
'repackaged' indicates anagramming the letters (I've seen this in other clues).
'unopened' means to remove the first letter.
'dinners' with its initial letter taken off is 'inners'.
'tv'+'inners'='tvinners'
'tvinners' with letters rearranged gives 'VINTNERS'.

'and' is the link.

Can you help me to learn more?

(Other definitions for vintners that I've seen before include "14 [SWANUPPING] company" , "trades in port, perhaps" , "Wine merchants" .)

I've seen this clue in The Telegraph.
