How To Join Costco Without Paying The Full Membership Fee

It's no secret that in the grocery business, Costco garners a dedicated fandom. Offerings like its globally varied food court items, well-priced Kirkland Signature alcohols and incredible butcher counter all warrant the enthusiastic reception. Yet, as with other warehouse retailers like Sam's Club and BJ's, there is a membership fee. Thankfully though, there are ways to circumvent, and be able to join Costco without paying full price.

The secret lies in patiently awaiting a Groupon deal. The coupon platform offers discounted Costco memberships — usually accompanied with store credits — around once a year. Each time, the specifics of the deal looks a little different, and they can run for varying durations. For instance, the promotion available in fall 2025 offers $100 on hauls over $200 with the purchase of the standard Gold Star Membership. So go on a generous haul first shopping Costco trip, and you'll repay the investment. Alternatively, look into discounts on the platform Stack Social. While the savings are more modest — a $20 digital card in September 2025 — promotions run for longer. Either way, once procured, don't forget to explore all the perks that come with your Costco membership, thereby making the most out of the card.

If you shop at Costco frequently and cleverly, then the membership fee can pay for itself. Buying in bulk and from private label brands makes Costco more affordable than regular grocery stores. However, the retailer isn't an ideal fit for everyone: Maybe you don't often need large quantities or the store's location and hours are inconvenient.

So for infrequent Costco shoppers, consider splitting the membership with others. The one legit way to share your Costco membership is through a household address. A partner, family member or even roommate can receive a copy, and use it for independent shopping trips — thereby effectively halving the annual fee.

Furthermore, take note that Costco also allows you to enter its stores with two visitors. Although they can't pay for the shopping transaction, you can certainly split the grocery haul after leaving store premises. The savings already lie in big batch purchases; so such group excursions really squeeze the most out of the retailer. Not to mention, this is a terrific way to cut down on shopping waste, thereby really optimizing Costco's available products.
