One who cares to make an offer? (6)
I believe the answer is:
tender
This clue is a double definition.
'one who cares' is the first definition.
(I've seen this before)
'make an offer?' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for tender that I've seen before include "Hurting" , "Bid; kindly" , "carer's > inexperienced" , "sensitive > carer > money" , "Gentle and sore" .)
