Will likely be $13 + $25 hazmat fee. This fee sucks, If I order a $5 pack of primers for ammo reloading, it'll be the same fee. However, this fee usually applies once for the order as it's per box. So if you order one small bottle or order 4 gallons, it SHOULD only be charged once per order.
Oh and I run the Traxxas 20% and am very happy with it.
