The Lowes in Orchard Park has a glass cutting area and people to answer questions. I was just there yesterday.
They have a window repair section I'm not sure about glass to be cut
Not that I am aware of or to my knowledge there's always the lancer glass on Broadway in depew by the DNL plaza
They have window repair kits and glass there. I'm sure one of the technicians there have knowledge to help guide you.
