If I remember correctly you have to email them or pay the unshipped amount then pay again when they email you the shipping cost.
I've ordered from them in the past and had alright results. I've always received my order sooner or later, but they hardly respond to emails after you've paid. Many people have had nothing but problems dealing with them and because of that I won't order anything from them anymore. Search Evike on here and then you can decide if it's worth while.
