Cheap decoration can find a buyer, mostly (6)
I believe the answer is:
tinsel
'cheap decoration' is the definition.
'tinsel' can be an answer for 'decoration' (I have seen 'Showy decoration' mean 'tinsel' so perhaps 'decoration' could also mean 'tinsel'). I am not sure about the 'cheap' bit.
'can find a buyer mostly' is the wordplay.
'can' becomes 'tin' (both are metal containers).
'find a buyer' becomes 'sell' (I've seen this in another clue).
'mostly' means to remove the last letter (most but not all of the word).
'sell' with its final letter taken off is 'sel'.
'tin'+'sel'='TINSEL'
Can you help me to learn more?
(Other definitions for tinsel that I've seen before include "Cheap and gaudy metallic material" , "Cheap shiny stuff" , "Sparkly decoration" , "Christmas (or Hollywood?) decoration" , "At Christmas it might be seen" .)
