That's the rate to ship any thing from Kinshasa to Kananga by air. It's only 400 miles. But there are no roads, no trains or other means of transporting goods. By boat is too slow and cumbersome.
It cost me more for shipping then the item cost. Luckily it was raw materials for building our bio-sand filter molds. Water filters will save countless lives. That makes it easier to accept.
