If you're looking for a great deal on appliances, Costco is definitely worth checking out. They carry a wide range of appliances from all the major brands, and they are almost always cheaper than buying directly from the manufacturer or through a big box store like Best Buy.
One thing to keep in mind, however, is that Costco's prices can vary significantly from region to region. So if you're looking at appliances online, be sure to check the price at your local Costco before making any purchase decisions.
