What does it cost for a membership?

What Isaac said.

https://www.costco.com/join-costco.html Sometimes there are incentives throughout the year to join. Like $25 gift card. Some employers also have agreements with Costco to get additional savings.

Accounts include: Gold Star Business - $60 / year Executive - $120 / year Executive includes 2% cash back on purchases at Costco. You get a check in the mail for the 2% of purchases each year. So as long as you spend at least $6,000 / year or $500 / month at Costco, your membership fee of $120 / year pays for itself after the 2% cashback. Costco is also offering a Costco gift card to new members who sign up by June 30, 2019 - Gold Star = $10 gift card Executive = $20 gift card See this link for more info including student and military membership options. https://www.costco.com/join-costco.html
