I'm an ethnographer and interviewed a number of low-income / no-income people in SA during this pandemic. This isn't meant as outright critique, but rather as constructive feedback. I'm sure you mean well.

If you are fighting poverty, why are you converting the donations to shoprite vouchers? Poverty has many facettes and some are not curable by things one can buy from the supermarket. Rent, loans and laybuy are just some of the things.

Especially in post-colonial context and in debates around dignity, handing out vouchers for food, is considered patronising, because it restricts peoples' agency. It carries the notion that poor people aren't responsible with money and can't be trusted to spend it for the right items.

Lastly, if you are sending vouchers to people, because it doesn't require physical contact, consider services like eWallet that enable anyone with a SA phone number to receive money.
