I have not seen any posting on the Duty Free shop hours in over a year. They use to close upstairs at 9:00 p.m. and down stairs, in the baggage claim area, at 10:00 p.m. They stated they would remain open a little later downstairs if a flight was scheduled to arrive.
Now more flights have been added that arrive after 9:00 p.m.. I am not sure if they have adjusted their schedule. Hopefully someone will be able to give you some more up to date info.
