The cost depends on if they have second hand glass
As a glass merchant spending about $300,000 per year on glass, that piece would cost me more than what some people are quoting.
If your buying new glass, anything in the $70 to $90 would be a great price with the retail cost being somewhere $130 plus GST
I dont stock or sell second hand glass as storage is not worth it and it takes up valuable space that new glass could use. Afterall, if you have some nice new doors installed and want glass in them, the last thing you would want is scratched second hand glass in them
