Does anyone know a local craft store where I could buy 8x8" boxes, about 1-2" high, to put single photo books in for presentation to clients? Michaels only has 12"x12" for square sizes (everything else is rectangular). I know you can get them at Rice Studio Supply and other online retailers, but the shipping is atrocious ($65 for UPS). My album printer sells them individually with each book I order, but I'd like to buy in bulk if possible. Thanks for any tips!
