do you sell cut mirror to size? if so what would a piece 12 1/2" X 37 !/2" cost ?

I tried to find a certain small size last year and ended up going to a craft store like Hobby Lobby or Michael's.

The smaller true value and ace hardware stores do.

No, call andys glass or glasswise

Probably not I would call Lowe's or home depot for that

I don't know vas the store.

I'm not sure. I would call the store directly.
