Discount stores sell a range of everyday goods at prices that are generally lower than those found at many traditional retailers. Their stock can include food and drink, household cleaning products, toiletries, stationery, toys, clothing, kitchenware and seasonal items. Some stores concentrate on a particular type of product, while others offer a changing mix across several categories. Lower prices may be achieved through bulk purchasing, simpler store layouts, limited product ranges, own-brand goods or the sale of surplus and end-of-line stock. Availability can vary between branches and over time, particularly where items are bought as short-term or seasonal lines. Customers may find both branded and unbranded products, including multipacks and practical everyday essentials. Some discount stores also sell chilled or frozen food, small electrical goods, home furnishings and basic DIY supplies, depending on their size and focus.
