unfortunately that is the price of shipping.
I am trying to get a lilliput casing and it is going to cost me US$35 in shipping for something that weighs a couple of hundred grams.
As for the store checking it. I suppose it could be done, it may cost you tho. email them at firstname.lastname@example.org to ask. Threads on here do not always get answered by the store staff.
BTW Zakros, where do you live? maybe we could share the shipping.
