I am having trouble with the free shipping. I think it is due to the window not being free shipping. I cannot make the window "free" because someone will start ordering windows alone. If you were charged shipping I will refund it.

Shame about the US only thing, but I appreciate the extra hassle international shipping would entail.
I ordered some aluminium composite sheet cut-to-size locally (Melbourne, Australia), and it worked out to less than $100 with delivery. Still have to drill holes, cut slots, etc. but the stuff is very pleasant to work with.
