Weigh-and-Pay Shops Tackle South Africa's Poverty Tax 2026

Weigh-and-pay shops in South Africa are emerging as a powerful solution to the poverty tax that forces low-income families to pay more for basic necessities. In Johannesburg's Alexandra township, residents like Tsholofelo Mphela visit bright yellow shipping containers to buy just a few spoonfuls of sugar or a cup of rice, rather than being forced to purchase larger, unaffordable quantities. This innovative retail model is directly tackling food insecurity and malnutrition in some of the country's poorest communities.

What Are Weigh-and-Pay Shops?

Weigh-and-pay shops, such as Gcwalisa (meaning "fill up" in isiZulu), allow customers to purchase precise amounts of staple foods—from beans and rice to cooking oil dispensed by the millilitre. The cashier weighs the selected items and charges only for what the customer can afford. This approach eliminates the poverty tax, where the poor often pay more per unit because they can only buy small, expensive packages.

The Poverty Tax Explained

The poverty tax refers to the extra costs incurred by low-income households when they cannot afford bulk purchases. For example, a 2kg bag of sugar costs about 60 rand, but many families cannot afford that upfront. Instead, they buy small sachets at a higher unit price. Weigh-and-pay shops remove this penalty by offering the same unit price regardless of quantity.

Impact on Food Security

A 2024 national survey found that nearly two-thirds of South African households experience food insecurity, with almost 30% of children under five suffering from stunting due to chronic malnutrition. By making healthy food accessible in small, affordable amounts, weigh-and-pay shops help families like Mphela's—where a monthly bulk grocery shop lasts only a week—put nutritious meals on the table.

How Weigh-and-Pay Shops Work

These shops source staple foods in bulk and sell them loose. Customers bring their own containers or use provided ones. The process is simple:

• Select the desired food items from jars or dispensers.
• Weigh the items at the counter.
• Pay only for the exact amount taken.

This model reduces waste, empowers customers, and ensures that even the poorest can access a varied diet.
