Made a higher offer (6)
I believe the answer is:
outbid
'made a higher offer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for outbid that I've seen before include "Offer more for something than (another person)" , "as 14 might do to 3 or 26" , "But I do (anag)" , "Go higher than another at an auction" , "Make a higher offer than another" .)
