Costco is your literal one-stop shop for everything under the sun - in huge bulk and in tiny prices. Established as a household name worldwide, it is the second largest retailer in the United States (the largest membership-only warehouse club chain in the US), and the seventh largest retailer in the world. It has locations all over the world, in countries including the United Kingdom, Australia, Canada, Mexico, Taiwan, South Korea, Japan, Spain and the United States, where it has more than 450 stores across the country. It is known for selling products at low prices, and more often than not, products are sold in bulk or large volumes, which is perfect for families and businesses. Many traditional retailer hassles are totally cleared away at Costco, with truly a no-frills, no-nonsense shopping experience, allowing Costco to limit its price markup to no more than 15 percent, hence providing the best shopping satisfaction for all.
