even if they are providing good service, we are bound to go out and
get "the best deal" so we put out an open tender thingy..
sometimes we do get a better deal, a much better deal.. like a
bunch of signs we made..
the original company quoted us about $1,950 for each
standing sign we wanted to replace smashed one (1 got hit by a car)
and there were a few more requested..
we put out an open tender and a company made the exact duplicate
for $750 each
however, for the computer system one, i think it was a
mistake 
yeah. I can stick to the same vendors only for work that will
cost less than 3k. (no need to call for ITQ)
