Thanx for the tip, will try Luno. I see they are the prefered platform.
If you want to by LTC local the only option is ICE3X but they have highish margins so take care to compare prices.
If you're using ZAR rather buy BTC from Luno and move it to an exchange where you can swop it for other currencies like LTC.
Actually, a better way of doing it is to move your BTC away from Luno to a wallet where you control the private keys.
One option is to use
http://www.exodus.io/ which - a desktop wallet with great features. You control your own private keys and can use Shapeshift to convert to other supported crypto at low cost. (If you have USD or EUR then buy BTC from Bitstamp.com as it's around 6% cheaper than Luno on avg).
If you want access to all kinds of obscure crypto you can register at
https://bittrex.com/
