Hello South Africa Collector !
I can offer you in exchange from my eStore - around 3500 items for items I still need from South Africa or homelands.
Furthermore I can offer you New Issues of New Zealand and also back issues as available.
Idealy South African collectors would have such material but anyone interested in Australia, New Zealand or the Pacific is welcome to contact me to negotiate some stamp trading deal.
In Deutsch ist auch kein Problem.
Enjoy your hobby!
