Selection of soya beans on counter in marketplace (4)
I believe the answer is:
ebay
'marketplace' is the definition.
(I have seen 'Online marketplace' mean 'ebay' so perhaps 'marketplace' could also mean 'ebay')
'selection of soya beans on counter' is the wordplay.
'selection of' indicates a hidden word.
'counter' says the letters should be written backwards (counter can mean in the opposite direction).
'yabe' is hidden within 'soya beans on'.
'yabe' backwards is 'EBAY'.
'in' is the link.
(Other definitions for ebay that I've seen before include "Internet sales facility" , "Auction site" , "Modern marketplace" , "Online selling site" , "Website" .)
