I recently stood in the vegetable aisle of a major retailer in Gaborone, looking at a pre-packed bag of potatoes. There were exactly eight potatoes in the bag, neatly washed and graded, priced at nearly 40 Pula. It is a common scene for the middle-class shopper: you pay for the convenience of the plastic, the air conditioning, and the “Grade A” label. Yet, less than five hundred meters from that store’s entrance, a street vendor was selling a 10kg “pocket” of potatoes for that exact same 40 Pula.
The math of this transaction is staggering. In the aisle, I was paying for roughly 1.5kg to 2kg of starch. On the street, for the same amount of currency, I could have secured five to six times that volume. As a business journalist, I had to ask: how did we reach a point where the “convenience” of a supermarket results in such a massive disparity in food volume for the Motswana consumer?
The Two Economies of the Potato
The Probe looked into this price gap not to criticize the business models of retail giants like Checkers, Spar, or Pick n Pay, but to audit the infrastructure that makes their produce so expensive. What we found are two entirely different supply chains operating in parallel, each with its own set of hidden costs and benefits.
The large retailers operate a high-overhead machine. When you pay 40 Pula for eight potatoes, you aren’t just paying for the crop. You are paying for the industrial cold storage that keeps that potato firm for weeks, the international logistics that often bring produce across the border from South African distribution centers, and the high electricity costs of keeping a 2,000-square-meter store illuminated and chilled. There is also the “theatre of cleanliness”—the labor required to wash, grade, and package produce so it looks uniform under a fluorescent light. For the retailer, this is a business necessity; for the consumer, it is an invisible tax.
The Street Ledger
On the street, the ledger is stripped bare. The vendor selling a 10kg pocket for 40 Pula has no cold storage, no plastic packaging, and no electricity bill. They are often sourcing directly from local Botswana farmers who are bypassed by the centralized procurement systems of the big chains.
This creates a massive volume advantage for the street economy. While the retailer sells potatoes by the “pack,” the vendor sells by the “pocket.” For a family in Gaborone trying to stretch a budget, the choice should be obvious. However, the street economy lacks the one thing the retailer has perfected: predictable access. The street vendor may have 10kg pockets today and nothing tomorrow. The retailer, through its expensive and rigid supply chain, guarantees that those eight potatoes will be there every single day, regardless of the season.
The Market Reality of Choice
This brings us to the “Poverty Premium”—a cruel irony of the Gaborone market. Those who have the least amount of disposable income often find themselves shopping at the big retailers because they can only afford to buy in small increments. They may not have the 40 Pula to buy a 10kg pocket at once, or the transport to carry it home, or the storage to keep it from rotting in a hot kitchen.
Instead, they buy the small, expensive retail pack. They end up paying the highest price per unit because they cannot afford the “bulk” savings of the informal market. The retailers are not necessarily price-gouging; they are simply passing on the costs of a high-spec, centralized distribution system that is poorly suited for a low-liquidity consumer base. They are in the business of safety and consistency, but that consistency comes at a premium that effectively shrinks the Motswana pocketbook.
Balancing the Equation
Ultimately, the gap between the retail aisle and the street corner is a reflection of Botswana’s maturing but divided food system. The large retailers provide a vital service in terms of national food security and formal employment, but their pricing structures on basic staples like potatoes and tomatoes reveal a disconnect from the average citizen’s economic reality.
We have to ask if the “Grade A” grading system is serving the consumer or simply justifying a higher markup. A potato from a 10kg pocket on the street provides the same nutritional value as a washed potato in a plastic bag. At The Probe, we believe the question isn’t why the street is so cheap, but why our formal retail systems have become so expensive that they turn a basic staple into a luxury item. The street vendor isn’t just an informal trader; they are a vital shock absorber for the Botswana economy, providing a volume of food that the formal retail machine simply cannot match for the same price.
