I am planning on buying a few IKEA goodies and take then on the plane, its way cheaper then buying furtniture in Luanda.
Perhaps you can try and buy them in Namibia, in the capital,windhoek (I think its less then 2hours flight)...not sure how import tax works, let me know if you figure that out, am moving in less then 8weeks, thankfully sqatting at company accomodation but have to find my own place after a month or so.
All the best.
