I want to buy a full bottle of Montale directly from Montale with the free 20 ml bottle... which one should I get as the 100 ml and which one as the free 20 ml? I'm interested in the Black Aoud and the Dark Aoud... I already have a 3.4 oz bottle of Bond New York Oud which I find similar to Black Aoud... so the question is which one should I get as a 100 ml and which one as the 20 ml? Black Aoud or Dark Aoud?
