Bonjour Jean!
Comment vous allez vous? Je connais un website super pour acheter des cds:
http://www.oneworld.co.za
It's a South-African site, and I believe they'll ship anywhere. They've got a nice little selection of kwaito!
If you like kwaito you might also like a band called "blk sunshine" - it's great stuff!
Hope this helps!
Salut
Liza
