Unique ways to save with Costco promo codes and more

Become a Costco member to save

Costco is a membership-based place to shop. Once you join, you’ll have access to tons of savings, bulk discounts, and Costco coupons. A Gold Membership is $60 a year, and you get great discounts on gas, tires, everyday items, and more. You can also have Same Day or Two-Day deliveries on grocery items and find great deals on trips through Costco Travel. They even work with service providers to set you up with all your home and auto insurance needs.

If you pay an additional $60 a year, you can upgrade to an Executive Membership, which comes with a 2% annual reward (up to $1000) on qualifying purchases.

Get more cash back with a Costco credit card

Get a Costco Anywhere Visa Card by Citi, and earn cash back for all your purchases. It’s easy to do through the Costco website and once you’re set up, you can get 4% back on eligible gas purchases, up to $7000 a year (it’s 1% after that); 3% back on restaurants and eligible travel; 2% on all other purchases from Costco; and 1% on all other purchases.

The card doubles as your membership card, and there are no annual fees with your paid Costco membership. You’ll also have exclusive rewards. Use the card when you check out with a Costco promotion code on your orders. You can get a card with a personal or business membership.

Top ways to save at Costco

  • On top of getting regularly low prices, members can take advantage of an ongoing sale for online purchases. Get up to $250 or even $500 off big ticket items like workout equipment, TVs, and home appliances that are in-stock and ready to ship within three to five days. No need to use Costco coupons as the savings will be automatically applied.

  • Costco makes it easy to find savings on the website by grouping all sales items together in the Deals section. It has everything from beauty to baby products, and even furniture. Get $400 off a sectional or $3 off batteries. Even better, some of the Costco promo codes can be found online and in-warehouse.

  • Costco has a special promotion for teachers and students. Buy a Gold Membership and get a $30 Costco Digital Shop Card that you can use for your dorm room or to get school supplies. Just verify your status with UNiDAYS for students and ID.me for teachers when you sign up.

  • If you are a medical professional, you can access tons of special offers and Costco discount codes. Go to the website and verify your status as a nurse, medical provider, or hospital employee when you buy your membership to have access to these savings.

  • Members of the military, government employees, and first responders can get a Costco Digital Shop Card for $20 when you sign up for a Gold Membership. Just verify your status on Costco.com when you sign up, and be sure to agree to auto-renewal to qualify.
