If anyone is still interested in buying LKY's books they are still available at Popular. In fact they are prominently displayed in the best sellers section.
There was a rich old lady I know of years back, who bought many copies of the late old fart books in CHINESE. I asked her P.A. ( personal assistant), "old lady read CHINESE??. She is pranakan, don't read a word of Chinese...buy, just to support late old fart, most likely use them for her furniture that has uneven legs or a door stopper....ha ha ha.
The books had been at Popular's best seller section for years, it is a lie , that it is a best seller..... Singpost will issue a set of stamps with one 1st Local stamp featuring the late old fart & a Miniature sheet of $2 too, "supporters" can go buy them, lick or stick them all over the place..
