I recently re-did both my doors and came up with a whole new pattern for the glass. The new glass fits better to the shape of the opening, and goes a little further down (when lowered) into the door because of the new curvature.
Autotemp charges me $80 per piece of glass ($160/pair) to make them. They charge $400 shipping and crating whether its for 1 piece or 20 pairs. I divide that shipping cost over the amount of pairs ordered. If somebody orders 1 pair, it would cost $160 for the glass plus $400 for shipping for a total of $560. If I order 10 pairs, it would cost 1600 for the glass, plus $400 for crating and shipping, for a total of $2000. Divide that cost among the 10 pairs and each pair would cost $200. Shipping from here to anywhere in the continental U.S. is $46, bringing the total to $246/pair (to your door).
I dont make any money or mark up the glass even 1 cent. I make the crates to ship them at work so that doesn't cost me anything, and I dont charge for that either. The order process takes 4-6 weeks to the glass to arrive here, and for me to ship to you usually takes 4 days.
