I ordered a iphone from international-orders.com and choosed to pay using google checkout, but google checkout doesnt list the tax.

I only payed $698,59 out of $746.28. The tax is $47 why isnt it listed in google checkout?

I've only payed for the iphone and shipping, how do i pay the extra $47?

I live in sweden and the store is american.

Thankful for all answers.

Best regards
