Download South African postal codes list for free

I’ve seen various requests for the postal codes of South Africa (or zip codes) to be made available in a downloadable format but couldn’t find any available for free. 
There’s the official South African Post Office (SAPO) page that allows you to only search for the one you are looking for: Search by location name or by post code
As well as the listings on SouthAfrica.co.za

So, I decided to create my own and make it available to all for free download here: http://www.mediafire.com/file/201gi68niys161n/SapoPostalCodesSouthAfrica19Nov2011.xls

Did you know that there are 16,740 postal codes in South Africa?

Please post comments if you notice any errors or omissions.
