These are good guys to deal with.

Apart from the porolay gel, I've got all those other filaments. You're going to have fun :-)

International shipping is brutal !
It's even more expensive to ship from the states to the uk than from the uk to the states.
That said they do seem to be using the top end of the postal range.
I shipped 5.5 lbs to the states in december for about $65 - All your samples together with the packing can't be more than half a pound.
That said, I use untracked airmail, I think it was an extra £20 ($35) for the tracked.

Like I said, it's brutal. And believe it or not it's almost as expensive to ship from the states to canada - and that doesn't need to go airmail.

This is the only reason I haven't bought a roll or two of the polymakr polyflex - by the time I've paid tax and postage the cost per roll has doubled.

Shipping cost for the uk by globalfsd are pretty good. But that doesn't help you foreigners :-)
(everyone is a foreigner somewhere)
