Flyer's bargain at end of sale (5)
I believe the answer is:
snipe
'flyer's' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'bargain at end of sale' is the wordplay.
'bargain' becomes 'snip' (slang term for a good deal).
'at end of' suggests the final letters.
The last letter of 'sale' is 'e'.
'snip'+'e'='SNIPE'
Can you help me to learn more?
(Other definitions for snipe that I've seen before include "To pick off soldiers, say" , "Criticise" , "Shoot; birds" , "Pines for bog bird" , "Pines like wading bird" .)
