Change the amount of the order

[cuprum]

Hello.

I just did the order # 7889.
Unfortunately, I not it right considered desired to me the number of Mould Clamp.
I need 12 pieces.

How do I change the amount and pay the remaining amount? In order to send the entire order one parcel?

You do not remove the VAT from foreign clients?

Best Regards, Michael.

P.S. And I would like registered mail. I'm waiting for an invoice Paypal.
