Offer more: you'll get a lot from it (6)
I believe the answer is:
outbid
'offer more' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for outbid that I've seen before include "But I do (anag)" , "Offer more then competitors at auction" , "Offer more than (another in auction)" , "Go higher than another at an auction" , "Make a higher offer than another" .)
