WANT TO BUY, Goliathidae, African beetles/ Butterflies/Insects

Hello, I am looking for long-term and above all honest 
business relationships in Africa. After I was cheated 
again in Cameroon (goods paid, but not received, 
after some parcels 
went well beforehand) please only write without 
prepayment. I'll never do that again. 
When I receive the goods, payment is made, no 
prepayment. So don't even write to me with prepayment. 
I am happy about fair offers with normal prices. 
Best wishes
