At NUS, they didn't have a service for colour transparencies,
while B/W transparencies would cost 60 cents each.
I paid 50 cents per B/W transparency at Katong.... in other words,
it's actually cheaper to do it there than in school.
Dang.... even though I use B/W transparencies, I still have to
shell out $6 because I have twelve of them. 
It is not lost on me that it would have cost me nothing at all if I
had been allowed to use Powerpoint.
