Economical type — watch — in pursuit of pub profit (7-6)
I believe the answer is:
bargain-hunter
'economical type' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'watch in pursuit of pub profit' is the wordplay.
'watch' becomes 'hunter' (type of watch).
'in pursuit of' says to put letters next to each other (some letters chase after others).
'pub' becomes 'bar' (both are drinking establishments).
'profit' becomes 'gain' (synonyms).
'bar'+'gain'='bargain'
'hunter' after 'bargain' is 'BARGAIN-HUNTER'.
Can you help me to learn more?
(Other definitions for bargain-hunter that I've seen before include "Person attending the January sales, perhaps" , "One after a cheap deal" , "Attender of sales" , "One looking for a snip" .)
