A social enterprise in South Africa is challenging the so-called poverty tax by selling food and household goods by weight in small, affordable amounts, allowing residents of Johannesburg's Alexandra township to buy only what they can afford rather than paying a premium for smaller packaged portions.
The operation runs six shops from bright yellow shipping containers across the township. Inside, shelves are lined with large jars of beans, rice and maize meal, alongside clear boxes filled with breakfast cereal and loose teabags. A tap dispenses cooking oil by the millilitre. Customers take their purchases to a cashier, who weighs them before ringing up the total for a few rand.
The model directly addresses a well-documented problem: poorer households often pay more per unit for basic goods because they can only buy in small quantities. A single sachet of sugar or a small bag of rice costs proportionally more than a bulk purchase, a hidden surcharge that campaigners call the poverty tax. By selling loose goods by weight, the shops let customers buy exactly what they need at a price that matches their daily cash flow.
For residents such as Tsholofelo Mphela, who runs a laundry shop in Alexandra, the container store has become part of the morning routine. On her way to work, she stops to buy a few spoonfuls of sugar. The purchase is small, but it fits her budget and avoids the waste of buying a larger packet that she cannot afford upfront.
The shops are operated by a social enterprise rather than a conventional retailer, a structure that allows them to prioritise affordability and access over maximum margin. The use of shipping containers keeps overheads low and allows the outlets to be placed directly within the communities they serve, rather than requiring residents to travel to larger supermarkets or shopping centres.
Food insecurity remains a pressing issue in South Africa, where many households struggle to cover basic necessities. Township residents frequently rely on informal traders and spaza shops for daily goods, but those outlets typically sell pre-packaged items in fixed sizes. The weigh-and-pay approach offers an alternative that gives customers control over both quantity and cost.
The model also has environmental implications, since selling loose goods reduces the need for individual plastic packaging. Customers can bring their own containers or use simple bags, cutting down on the waste associated with small-format retail.
Whether the approach can scale beyond Alexandra remains an open question. The six container shops represent a modest footprint, and the economics of weighing and dispensing loose goods require careful handling to remain viable. But for now, the bright yellow containers offer a practical response to a daily challenge: how to eat well when money is tight and prices are set for those who can buy in bulk.
