Fuel promotions have long been an important weapon in the supermarket industry’s battle for market share. Tesco operates one of the largest supermarket petrol station networks in the UK, giving the retailer a powerful advantage over competitors that have a smaller forecourt presence. By linking grocery spending with fuel savings, Tesco encourages shoppers to consolidate more of their household spending within its ecosystem. Loyalty programmes, personalised discounts, fuel rewards, mobile apps and financial services are becoming integrated parts of the modern grocery business. By connecting fuel discounts to loyalty activity, Tesco gains valuable data on customer behaviour while encouraging repeat visits.
