Does anyone know where I can buy a3/8"x5x5 sheet of Baltic birch plywood

I thought Home Depot and Lowe's and any good sized lumber yard sold Baltic birch, but I just checked and I guess they don't. I must have seen it at my local lumberyard. Google it to find a place nearest to you.

I agree with joypulz.

Search your area for multiply plywood, also know as 5 and 7 core birch plywood. Search for cabinet makers supplies. In my area it is carried by A&M Supply, formerly known as Allied Plywood.
