I'm certain they get a large discount, but that's not going to be related to the shipping cost. The best deal for them is likely to be to negotiate the price "Ex Works", which means the customer handles transportation and clearance from the factory gate. That way they can negotiate their own prices for the shipping, and handle the customs clearance in the way that works best for them. I doubt they're literally chartering a 747. I can't see how that would be better than just shipping them as normal air freight.
