Rather than take the time to see if I could save a few bucks by having this relatively heavy and inexpensive coolant shipped, I chose just to go down to my local Porche dealership and buy a gallon. It was around $30. They gave me the normal PCA 10% discount.

Make sure that you are aware of the potential problem of air bubbles in the cooling system of the M96 engine that are difficult to remove without the special apparatus that the dealerships have. This engine is notoriously difficult to get all of the air expelled after a coolant removal. The air bubles can cause serious overheating if not properly removed. You can search for the topic on this forum or on Renn Tech, for example. I chose to just have the dealship do the flush and air removal rather than buy the apparatus and play around with it.
