One strategy that supermarkets use to sell more groceries is offering discounts and promotions. The text states, "Many supermarkets will routinely discount certain items, often slashing prices by 50% or more to attract customers. This is because they know that customers are more likely to buy in bulk and make impulse purchases when they perceive a sale or bargain." This evidence suggests that supermarkets use discounts to entice customers to purchase more items and take advantage of perceived sales or bargains.
