Supermarkets
UK supermarkets sell food and household goods through large stores, convenience stores and online delivery. The market is mature and slow-growing, so the main chains compete hard for market share, mostly on price, range and convenience. Margins are thin, so small changes in cost or price have a large effect on profit.
Supermarkets across the 9BS0 specification
| Theme 1: Marketing and people | |
|---|---|
| 1.1.1Mass and niche markets | Groceries are a mass market: almost every household buys them weekly. Niches exist within it, such as organic, free-from and premium ranges, which some chains use to win higher-income customers. |
| 1.1.3Market positioning and differentiation | Chains position on a price and quality map. The discounters sit at low price; others differentiate through range, store locations, online delivery and loyalty schemes rather than price alone. |
| 1.2.4Price elasticity of demand | Demand for a single supermarket is fairly price elastic because shoppers can switch chains easily and compare prices online. Demand for groceries as a whole is price inelastic, because people still need to eat. |
| 1.2.5Income elasticity of demand | Food overall is a necessity (YED between 0 and 1). Within a store, value ranges can behave like inferior goods, and premium ranges like luxuries, so the mix of sales shifts as incomes change. |
| 1.3.3Pricing strategies | Competitive pricing and price matching against rivals are common, with psychological pricing (for example £1.99) on shelves. Loss leaders on staples bring customers in. |
| 1.3.5Product life cycle and customer loyalty | Loyalty schemes (such as member prices) are used to build customer loyalty and collect data on what customers buy. Own-label products are relaunched and repackaged as extension strategies. |
| 1.4.1Flexible workforce | Stores open long hours and are busiest at evenings, weekends and Christmas, so chains rely on part-time staff and flexible hours to match labour to demand. |
| Theme 2: Managing business activities | |
| 2.2.3Fixed costs, variable costs and break-even | Stores carry high fixed costs (rent, staff, refrigeration), while the goods themselves are the main variable cost. With thin margins, contribution per item is small, so a store needs high sales volume to pass break-even. |
| 2.4.2Capacity utilisation | Capacity is floor space, checkouts and delivery slots. Under-used stores spread fixed costs over fewer sales; in peak weeks, full delivery slots mean lost online sales. |
| 2.4.3Stock control and lean production | Fresh food is perishable, so poor stock control means waste. Chains use just-in-time deliveries from central warehouses several times a day, which keeps stock low but depends on a reliable supply chain. |
| 2.5.1Economic influences | Inflation in food and energy prices raises costs and pushes customers to cheaper chains and value ranges. Imported food becomes dearer when the pound depreciates. |
| Theme 3: Business decisions and strategy | |
| 3.1.4Porter's Five Forces | Rivalry is intense and buyer power is high, because switching costs are almost zero. Large chains have strong buyer power over suppliers. Barriers to entry are high for new store chains because of the cost of property and distribution. |
| 3.2.1Growth and economies of scale | Size gives purchasing economies of scale: large chains buy in huge volumes at lower unit cost. Growth into convenience stores and online increases market share but can bring diseconomies, such as harder communication across thousands of sites. |
| 3.4.4Business ethics and CSR | Ethical issues include food waste, plastic packaging, fair treatment of suppliers and paying staff fairly. CSR activity, such as donating surplus food, can protect the brand but adds cost. |
| Theme 4: Global business | |
| 4.3.1Global marketing and glocalisation | UK grocery is mainly a domestic market, but the German discounters show international expansion: they adapt ranges to UK tastes while keeping the same low-cost model, an example of glocalisation. |
| 4.4.2Supply chain ethics | Supermarkets source from global supply chains (for example fruit, tea and clothing), so they face pressure over labour conditions at suppliers and misleading labelling. |
Words to use for supermarkets

- Own-label
- Products sold under the supermarket's own brand, often in value, standard and premium tiers.
- Discounter
- A supermarket that keeps prices low by stocking a narrow range, mostly own-label, in simple stores.
- Footfall
- The number of customers coming into a store.
- Basket spend
- The average amount a customer spends per shopping trip.
- Like-for-like sales
- Sales growth from stores open a year or more, so new stores do not inflate the figure.
- Loss leader
- A product sold at or below cost to bring customers in, who then buy other items.
- Shrinkage

Example businesses in supermarkets
Real businesses to use as evidence (the P in MOPS) when a question gives you no data.
- Tesco
- Public limited company. The largest UK grocer, with large stores, convenience stores (Tesco Express) and online delivery.
- Sainsbury's
- Public limited company (J Sainsbury plc). Positions slightly above the discounters on quality and range.
- Aldi and Lidl
- German-owned discounters, both privately owned. A narrow range, mostly own-label, at low prices.
- Ocado
- Online-only grocer, run as a joint venture between Ocado Group plc and Marks & Spencer. Delivers from automated warehouses instead of stores.
Practice questions on supermarkets
4 marksExplain one reason why demand for a supermarket's value range may rise during a recession. Spec 1.2.5
Model answer
One full MOPS chain.
- MMake your pointA value range is likely to have negative income elasticity of demand, so it behaves like an inferior good.
- OOffer an explanationWhen incomes fall in a recession, customers trade down from branded and premium products to cheaper alternatives to keep their weekly food bill down.
- PProvide evidenceSupermarket chains sell own-label ranges in tiers, so a shopper can move from the premium or standard range to the value range without changing store.
- SState significanceThis means sales of the value range may rise even while total spending falls, which helps the chain keep customers who might otherwise switch to a discounter, although at a lower margin per item.
4 marksExplain one benefit to a supermarket chain of using just-in-time (JIT) stock control. Spec 2.4.3
Model answer
One full MOPS chain.
- MMake your pointJust-in-time means stock arrives only when it is needed, so the supermarket holds very little in each store.
- OOffer an explanationBecause fresh food is perishable, holding less of it reduces the amount that passes its date before it is sold.
- PProvide evidenceSupermarkets restock stores from central warehouses several times a day, so shelves can be refilled with fresh products based on what has sold.
- SState significanceThis cuts waste and storage costs, which matters in a market with thin profit margins, where every saving in cost has a large effect on profit.
10 marksAssess the benefits to a large supermarket chain of matching the prices of discount supermarkets on its most popular products. Spec 1.3.3
Model answer
Two developed MOPS chains, one each way, then a judgement in context.
Argument for
- MMake your pointPrice matching is a form of competitive pricing that could stop customers switching to the discounters.
- OOffer an explanationDemand for a single supermarket is fairly price elastic, because shoppers can compare prices online and switching costs are almost zero. Matching on the products customers buy most often removes the main reason to leave.
- PProvide evidenceDiscounters such as Aldi and Lidl compete mainly on price, so a large chain that matches them on staples can still offer its wider range, its online delivery and its loyalty scheme.
- SState significanceAs a result, the chain may protect its footfall and market share, and customers who come in for matched items are likely to buy other, higher-margin products in the same basket.
Argument against
- MMake your pointHowever, price matching reduces the profit margin on the matched products.
- OOffer an explanationA large chain has higher costs than a discounter, such as bigger stores and a wider range, so selling at the discounter's price may mean selling some items at close to cost or below it.
- PProvide evidenceSupermarket margins are already thin, so a fall in margin on high-volume products could cut total profit significantly.
- SState significanceThis means the strategy only works if it raises basket spend enough to make up for the lost margin, and the discounters could respond by cutting prices further.
Conclusion
- EEvaluateOn balance, price matching is likely to benefit a large chain in the short term by holding on to price-sensitive customers. However, in the long term this depends on whether those customers also buy higher-margin products in the same trip. If they only buy the matched items, the chain is fighting the discounters on their strongest ground, cost, which it is unlikely to win. The most significant factor is therefore the effect on total basket spend, not the price of the matched items alone.
