I used to fly in & out of CMB quite often (unfortunately, before I knew about, or joined FT), but chocolate prices there (arrivals DF) were the lowest I had seen for Duty-Free (definitely better than SIN!)...I did buy some whiskey/wine, but I cannot recall how good the pricing was, but I think it was decent...

Time for the FT'ers MR'ing down there to advise...I've refunded 2 of mine already...

Don't discount Indian airports nowadays either - they used to be outrageous, but have come down to market levels, I think-will check next time I fly & report!
