Online community opportunities for South Africans and shopping - SFI

About a year ago I registered on SFI and went on well for a while. Unfortunately this was even more expensive due to only a FEW merchants in South Africa from who you can purchase.
I know it is widely advertised, but for me this site just didn't do it. I also couldn't get a down-line even with advertising. You may try this for it is basically cash back in your pocket, but for me this wasn't worth the expenses.
