I would return and look to acquire new rebate (8)
I believe the answer is:
discount
'new rebate' is the definition.
'discount' can be an answer for 'rebate' (thesaurus). I'm not certain of the 'new' bit.
'i would return and look to acquire' is the wordplay.
'i would' becomes 'I'd'.
'return' says the letters should be written in reverse.
'and' becomes 'n' (common abbreviation for 'and').
'look' becomes 'scout' (I can't explain this - if you can you should believe this answer much more).
'to acquire' is an insertion indicator.
'id' backwards is 'di'.
'n' put within 'scout' is 'scount'.
'di'+'scount'='DISCOUNT'
Can you help me to learn more?
(Other definitions for discount that I've seen before include "Reject as unimportant" , "Do tunics attract reduction in price?" , "Reduction in cost" , "Reduction in price for conduits" , "Reductions as for cash" .)
