Cheapest postage is to buy stamps below face value.

You have a company that does that legally, for stamps that have not fallen
off the back of the truck?

Cheapest postage of all is UN stamps. If you are in NYC you use them at
UN Post Office. Only UN NY stamps can be used there.

I once saved over $70.00 by mailing a luggage cart full of envelopes
there.

Oh, THAT'S a good idea. That turns domestic mail into international mail
and subjects it to potential delay at customs, and possible loss of
privacy if they decide to open it.

Alternate shipping methods include Greyhound Bus. They hold at other
end for pick-up.

Greyhound is excellent for those near their terminals and if one can take
advantage of their route network. Obviously, it's not universal coverage,
and the areas in which they make pickups or deliveries at the door is
limited. They aren't the cheapest by any means. However, if you are
shipping along an actual route they are the only ones who can get it there
same day.
