Explanation:

A department store is a type of retailer that offers a wide range of diverse products. Each product group is classified into a department, thus the name "department store". When customers buy products, they usually check out near the exit of the whole department store, although there are some check-out counters in each department. Also, customer service is always present, mostly in the form of numerous sales clerks providing a helping hand.

They can include almost any range of products: toiletries, furniture, home decor, clothes, toys, hardware... Some famous examples are: Le Bon Marché in Paris, Selfridges in the UK, Macy's in the USA...

On the other hand, a discount store usually offers a broad product range, low prices, but little to none customer service. Specialty stores have a narrow target group as they offer a limited assortment.
