I believe he sends you the actual shipping quote once he is ready to ship.
I order some enclosures and also some vampire plugs ... and the vampire plugs won't be in for 2-3 months cause its a pre-order ... but I've heard that same as above.
I think you just have to trust that this works, but its not a retail experience.
I'm not worried about it because I don't even have my LE kits yes, let alone have them built. Then the enclosures and cords are the last thing for me.
I totally understand your concerns.
I heard he works out on an oil rig.
