A cut I arranged to get on the sale (7)
I believe the answer is:
auction
'the sale' is the definition.
(I've seen this before)
'a cut i arranged to get on' is the wordplay.
'arranged' indicates anagramming the letters.
'to get' says to put letters next to each other.
'cut'+'i'='cuti'
'cuti' is an anagram of 'ucti'.
'a'+'ucti'+'on'='AUCTION'
(Other definitions for auction that I've seen before include "Use caution at public sale" , "Occasion of lots under the gavel" , "event with lots involved" , "Public sale at which bids are made" , "Public sale by bid" .)
