I bought 2 bottles from this site, shipping would have been about the same for 1 or 2 bottles. I got the Super Blue and also TYP 200. The TYP 200 is exactly the same as Super Blue except it is yellow colored so it helps when you bleed the system to know if its completely bled or not.
I also bought some Speed Bleeder valves for my calipers.
Haven't driven my car yet so don't have any real world experience.
Price, shipping, and customer service were good. You have to call in to order, they don't do online orders.
