Sale that sounds weird to some? (6)
I believe the answer is:
bazaar
'sale' is the definition.
(bazaar is a kind of sale)
I can't explain the rest of the clue.
(Other definitions for bazaar that I've seen before include "Souk" , "Middle East market - fundraising event" , "exchange ..." , "foreign market" , "Street of small shops in the Orient" .)
