Who here don't like discounts? Well if you like discounts, you should love bulk purchase discounts. At Costcos, you will be able to find relatively cheap common household items at low low prices because you buy them in bulk. Hey, their full name is Costco Wholesale. So somehow somewhere Costcos became the shopping mall of choice for those with spacious SUVs and would want to save a little for the rainy day. Their product line includes almost everything you can find in the home and even the office. That includes furnitures, household appliances, car tires, car accessories, computers, groceries, office equipments, sports goods, home entertainment, toys and more. In fact, you should be asking what they don't sell. I am rather afraid that Costcos might one day take over the world, just like Walmart. You don't know what these business types are capable of. Oh by the way, they are America's biggest retailers of wine. Not surprising, they mostly sell cheap wine, which we commonly termed as hogwash.
