I have. You can add things to the cart and it will show the freight. I did an order of about 300 euros worth of film, paper and chemistry and the freight was about 35 euro. I found that the initial charge was high, but I could add quite a few items and that didn't change the shipping. There were in the process of changing shipping to the US, so it might be different now from last summer.
I picked up some of the Euro sized Ilford paper that isn't stocked here, like 9.5x12 and 12x16. I found the prices very competitive with what I can buy Ilford for on this side of the Atlantic.
