Question: is bj's affiliated with costco?
Answer: Costco and BJ's Wholesale are both membership-based warehouse clubs. An annual Costco membership costs $60, while BJ's costs $55 a year. Costco and BJ's are very similar, but BJ's stores have a Dunkin' Donuts kiosk instead of a food court, and stores have a self-checkout lane so that customers can avoid lines.
