Make sure you are really saving this Black Friday. This a message and warning to South Africans who will be looking to save and make some rands over this year's black Friday shopping spree scheduled for Friday the 25th November. Like many countries around the world, South Africa has adopted the concept of Black Friday, with the annual sale being one of the highlights of the year from a retail perspective. But are South Africans really benefiting from Black Friday sales? Are there real savings to be had?

We spoke to Dr Farai Nyika, an academic at Mancosa's Department of Economics.
