Special offers? Pub benefits (8)
I believe the answer is:
bargains
'special offers?' is the definition.
(I've seen this before)
'pub benefits' is the wordplay.
'pub' becomes 'bar' (both are drinking establishments).
'benefits' becomes 'gains' ('gain' can be a synonym of 'benefit').
'bar'+'gains'='BARGAINS'
(Other definitions for bargains that I've seen before include "They're cheap at the price, as in sales" , "Haggles over price" , "Special offers" , "Goods procured cheaply at sale" , "Advantageous purchases" .)
