Costco is a special kind of retailer unlike any other. It is not simply a chain of shops. It is a wholesale warehouse club. That means that rather than shopping in a slick retail shop you shop in the warehouse, and because of the lack of construction/decorative costs, and because Costco buys its products based on volume, the savings are passed onto consumers. The products are often sold in bulk, so rather than buy just one bottle of shampoo, for example, maybe you have to buy a set of 4 bottles of shampoo in order to get the special discount prices that Costco offers. One strategy that allows them to do this is to not sell competing brands for the same kind of item. This allows Costco to sell a large number of items from the same company, allowing them to purchase at volume discounts.
Costco is an exclusive membership based chain, meaning that you need to buy a membership. Its prices are great already, but you have to pay a membership fee which can be prohibitive if you don’t shop at Costco very often. But you can save even more with Costco coupons and special offers. You can find some at the links below. Enjoy your shopping at Costco’s exclusive warehous locations!
