I've been checking shipping costs for these and while it should be pretty cheap to ship these USPS within the US, $5.35 for Priority Small Flat Rate Box, international is going to be rather steep. Shipping to the UK for instance by USPS is $16.95. FedEx, which I must have done something wrong, states $82.45 to the UK.
IC2005.com claims the package weighs 1g which seems too light for what it is. It would still be cheaper than someone ordering just one and having it shipped to the UK, however. I have personally never shipped a package of any type international, so perhaps someone can offer some advice. Any thoughts, questions, suggestions?
