The nearly $60 surface shipping for the two artillery battle pods made me put the brakes on too. Definitely not paying $100 shipping for the standard shipping option.
I thought maybe there was some better deal than the preorder on the website for the pair, but that's it. I emailed them with my pre-order for the first battle pod (two years ago) but they just told me to go ahead and order them. There was no special link to a sale or anything.
