For US Buyers: I've always found it less expensive in the US to order directly from Amazon UK as opposed to the Amazon US store for import items.
With the STITI Deluxe Box it works out like this with shipping:
Amazon UK
http://www.amazon.co.uk/gp/product/B0144VVT96
Item(s) Subtotal: £54.16
Postage & Packing: £3.08
Total Before VAT: £57.24

Approximately US $89
Amazon US
http://www.amazon.com/Second-Toughes.../dp/B0144VVT96
