Wow the South Africa post office is slow. Their site says two and three months for a surface-mail item to a country abroad. Damn I should have spent the extra money on shipping.
Practically speaking, it depends entirely on import customs on the receiving end. I've never had it take 3 months, and I've had it as fast as 3 weeks to the UK, so it's hard to predict. I'll re-update your order in a moment and pm you your tracking details:)
