Dealer beating our price (8)
I believe the answer is:
croupier
'dealer' is the definition.
(similar to a dealer in a casino)
'beating our price' is the wordplay.
'beating' is an anagram indicator.
'our'+'price'='ourprice'
'ourprice' with letters rearranged gives 'CROUPIER'.
(Other definitions for croupier that I've seen before include "official at the gaming table" , "Person in charge of a gaming table" , "Casino dealer" , "Gaming table worker" , "I procure (anag.)" .)
