Does anyone know of a fluorescein dye manufacturer that will ship to canada other than eye supply. We currently purchase our supply from Eye supply zin Tampa, Florida however they`re charging us $141 per box (12x5mL) of 10% dye. They`re also not able to ship the amount we`re looking for because they don`t have enough stock. We typically purchase about 100-150 boxes every 3 months. Thanks in advance, Krista
