Food, clothing, pretty much all necessities except electronics and cars are very cheap in SA compared to the rest of the world. Excluding 3rd world dumps like India or China of course.
Even the rest of Africa is a lot more expensive to live in as I found out the hard way. The US and Europe are even more so. If you look at the comparative indexes you will see SA is usually at half or less of US prices.
Here is a PPP map (yes it's from Wikipedia and a few years old, but I couldn't find anything more recent). The bluer the country is the less expensive the general cost of living. Most of Europe is orange indicating similar price levels to the US and Scandinavia is red indicating stupidly high costs as we know.
