Hi Toshihiko,

Thanks for the quotation, which looks fine.

OK. This sounds good.

Excellent!

Yes, please ship to the University of Sheffield.

I am unable to pay by credit card, unfortunately. I will have to fax you
a purchase order, if that is ok?

Freight collect in pounds is fine. Our Fedex account number is
3054-6774-0.

Hope this is all ok/clear.
