From my experiences, international shipping (across the pond) is usually INSANE. I've been charged more than the item purchased before (for a $50 purchase). It is not the fault if the supplier, but that is what the post/shipping companies charge. Personally, I don't get it.
The initial $11 and change seemed low to me, while the $30 some odd seemed more plausible.
It does seem to me to be an internet order issue. To bad they didn't see it on the initial purchase order and inform you BEFORE processing, but I'm glad to see it was handled "gratiously" afterwards.


I hope you enjoy your new kit!
