Broke, but I do offer more (6)
I believe the answer is:
outbid
'offer more' is the definition.
(I've seen this before)
'broke but i do' is the wordplay.
'broke' indicates anagramming the letters.
'but'+'i'+'do'='butido'
'butido' anagrammed gives 'OUTBID'.
(Other definitions for outbid that I've seen before include "Offer more then competitors at auction" , "Go higher than another at an auction" , "But I do (anag)" , "Offer more than someone else" , "Make a higher offer than another" .)
