Thank you for your order! We are at the moment experiencing a backorder of the DSM950-200-2OZ, but we are expecting in very close to your requested dock date. Material is due to us for September 2, so we would be possibly late by a couple of days past September 4 requested date. We will ship immediately upon receipt, and will of course send invoice to you the day of shipping as usual.
Please feel free to contact me if you require anything further in the meantime.
