Couple boxes of Montecristo #5's (JUN 10) from the main tobacco/booze duty-free at Singapore airport. The Hong Kong airport actually had a better selection (*), but you have to find the right store (on the way to gates 1 to 4) which I didn't find until after I had blown my duty-free allowance at Singapore.

(*) Only the big brands are represented decently (Cohiba, Monte, RyJ - and Davidoff), but one (and only one) of the stores at the HK airport had RE's, LE's, and special packaging (like the Partagas jar). Prices were relatively high - the only deal (close to Internet prices) that I saw were the #5's at Singapore.
