Pricing errors through Craftcloud?

I recently was looking at Craftcloud and noticed that i.materialise was the supplier there for the Multicolor+.
They show several different “offers” from i.materialise with different shipping prices.
When I order from the i.materialise site the shipping to U.S. is $15.50.
The best price offer at Craftcloud shows the shipping as only $5.99 to U.S. Is this a special deal through them or this an error?

Hi Nosslok,

we are providing to craftcloud the same prices as that we display on our webpage.
This rather seems an error on the Craftcloud page.
Shipment to the US for Multicolor+ is done from Europe with UPS express saver.
5.99$ seems to be rather the shipment price for USPS within the US.

Regards,
Wim
