depending on your jurisdiction probably tax free.
UPS shipping could run about $25 ???

From a cost standpoint, putting metal just at the edges certainly is
a good idea. I just checked out the price from Metal Supermarket for
a 2' x 4' piece of 1/4" plate: $220 Cdn for mild steel, and $233 for
aluminum. Plus cutting. Plus taxes. That's a bit more than what I
was planning to spend on the CB....so
back to the drawing board. A little voice is saying, stop messing
with funny ideas and just stick to Bolger's plan....

Seems to me one could save dough on aluminum cost and have hefty result
by laminating up a board with 1/4" ply in center except at leading edge
and bottom where you could substitute 1/4 Al perhaps 2" or 3" wide for
collision resistance. Thin aluminum in center isn't going to do anything
for bending anyway. You'd probably have to use ply that was actually at
least 1/4". I've used fir underlay that seemed to be pretty water
resistant, although if it wasn't in the middle there'd be the usual
checking problems, plus with 3 equal layers it is pretty bendy one way.
But the outer plies will take care of that.
