Costco Supermarket is a chain of membership-only warehouse clubs located worldwide. It is currently regarded as the biggest membership warehouse club chain in the United States. It holds its main office in Issaquah, Washington, USA.
Megan Mercer Costco's prices are okay if you are buying things in bulk but that doesn't mean they're actually cheaper than in a regular supermarket. You can even find better deals online without paying the $55 annual membership fee.
Maria Lester I have been a Costco customer for years and have never had a bad experience. The place is always clean, staff are friendly and they have a wide selection of merchandise at a great value. It's Costco, you can never go wrong with this place!
