Sending large parcel from Kenya to Germany

Hi all,
I am looking for alternatives for sending a rather large parcel (25-30 kgs) from Msa. to Germany.
The contents is personal effects (clothes, shoes).
The rates that posta has given us is quite high (about double of what the German Post system would charge if it was the other way round). Example : Ksh. 25010 for 25 kgs
Does anyone know a better/cheaper alternative for this? Time does not matter, the clothes are not urgent, it is OK if it takes some weeks.
Thanks

Have you tried DHL?

you can ask a quote by AGS if you are not in the hurry

That sounds quite unreasonable. I would recommend DHL or maybe you ask around if there's anyone traveling to Germany(with a large luggage allowance) and if they can carry the parcel for you
