Okay, real talk: that $65 (or $130 for Executive) Costco card in your wallet is doing WAY more than getting you a cart full of rotisserie chicken and a $1.50 hot dog. We went digging through the fine print of a Costco membership and found a stack of perks that most cardholders never even open the app to find. If you’ve been paying for a membership and only using it to buy 48-packs of paper towels, buckle up — you’re about to feel a little richer.
1. Your Free Household Card Is Basically a Second Membership
Every single paid Costco membership comes with one free Household Card. That means the primary cardholder can add one other person — usually a spouse, partner, or roommate at the same address — at zero extra cost. That person gets their own physical card, their own membership number, and full warehouse access. Business memberships can add up to six people for $65 per card. If you’re currently the only name on your account, this is free money you’re leaving on the table.
“Buying a new Costco membership for each person who wants to shop with you could get extremely pricey. Luckily, you can add another user, but there are clear rules around who can be included.”
2. Two Guests Per Trip, No Membership Required
Don’t have a Household Card situation? You can still bring up to two guests along on any single trip. The catch: only the member can actually pay at checkout, so this works best for splitting a haul with a roommate or a friend who Venmos you back at the register. It’s an easy way to let someone test-drive the warehouse before they commit to a card of their own.
3. Shop Cards Let Non-Members Skip the Surcharge
If a friend or family member truly doesn’t want a membership, members can buy them a Costco Shop Card (basically Costco’s gift card). A Shop Card holder can walk in and shop without flashing a membership card and without eating the non-member surcharge that applies at self-checkout. It’s a sneaky-smart workaround that a lot of shoppers never think to use.
4. The Prescription, Hearing, and Optical Perks Are Wildly Underused
As a primary member, you get access to Costco’s Prescription Program, which can knock up to 80% off select medications — no Executive upgrade needed. Costco also runs free hearing tests, free follow-up appointments, and free hearing-aid cleanings, plus loss and damage coverage on certain devices. If you’ve never asked about these at your local warehouse, you might be sitting on hundreds of dollars in savings.
5. There’s an Actual Seasonal Markdown Calendar
Costco quietly clears seasonal inventory on a predictable schedule: patio furniture and outdoor gear get marked down in late August, winter gear drops in March, and holiday toys and décor get slashed in January. If you’re patient enough to shop a season ahead, you can regularly find 50% or more off things you’ll actually use next year.
6. Costco Direct Has Its Own Stack of Instant Savings
Shopping online through Costco Direct isn’t just a convenience play — plenty of items there carry instant savings on top of already-discounted online prices, separate from the coupon book you get in the mail or app. Pair that with the fact that grocery shoppers who order online tend to spend 15–25% less overall (no impulse buys, and you can see your running total), and it’s worth checking before your next warehouse run.
7. Your Card Can Book More Than Groceries
Costco Travel is open to any cardholder and regularly beats other booking sites on package deals for cruises, rental cars, and hotels — plus members-only perks like resort credits. It’s easy to forget your membership even covers this, but it’s one more reason that $65 fee pays for itself many times over.
Between the secret codes hiding on Costco price tags, the food court’s secret menu hacks, and now these membership perks, it’s clear Costco is one of those stores where the real savings are hiding just below the surface. Combine these hacks with a few smart meal prep rules and your membership might just be the best subscription in your budget.
Have you used any of these Costco perks before? Add a Household Card member, ask about the hearing center, or just start timing your seasonal buys — your wallet will thank you. Tell us in the comments which hack you’re trying first!
