AFAIK they usually come in SMD packages only - which in turn means 
they'll usually be sold in bulk. And anyway - why would you buy, say, 
one 74x1G00 NAND and one 74x1G32 OR gate when you can get a 74x00 4xNAND 
IC for the same (or even lower) price, and wire up three of the gates to 
simulate the OR gate? (The 74x265 is also a neat beast - with its two 
(N)AND gates and two inverters/drivers it's an ideal candidate to 
simulate quite a wide variety of 2-gate combos you can imagine).

I guess the single-gate ICs are mainly targeted at applications where 
space, routing, speed or EMI constraints are serious enough to forbid 
sharing the gates of a single multi-gate IC among different sections of 
the circuitry.
