When you get home look up the window businesses in your area. All of them throw away the old ones. I'm collecting glass screen doors and the cooler doors, like the one's at gas stations for that same reason.
You can either call them and if you can have them as they bring them back or just check the trash after they close.
As for my seed station(The Mobile Greenhouse), it's going to be my winter growery to keep the fresh going all winter.😀
