When to Shop at Costco

Wholesale members know that bulk shopping with Costco already allows them to find their favorite brands and products for less, but Costco also runs sales events that make their everyday deals even more appealing. Here's when to look for special deals while shopping at Costco:

Costco Black Friday Sale

The Costco Holiday Savings event takes place online and at warehouses, and it's one of the biggest and best Costco sales of the year. Black Friday is the best time to get hundreds of dollars off big-ticket items like electronics, jewelry, and furniture.

For this year's Black Friday blowout, Costco is offering deals like $300 off the HP Omnibook Touchscreen Laptop, $400 off the MSI Codex R2 Gaming Desktop, $300 off princess-cut 0.73-ctw 14kt gold diamond studs, and $200 to $250 off the Novafoam 14" Serafina PerfectTemp Gel Memory Foam Mattress. Costco even has Black Friday appliance sales, with select Frigidaire refrigerators and freezers $150 to $200 off.

Costco Cyber Monday Sale

Deals on electronics carry over to Cyber Monday with even bigger savings. The Monday after Thanksgiving is usually when Costco rolls out its biggest deals on Apple products. For example, this year's deals will include $100 off the iMac All-in-One Desktop and $80 off the Apple Watch Ultra 3.

Costco’s Cyber Monday jewelry sales this year include $800 to $1,500 off platinum and diamond engagement rings and $200 to $400 off yellow-gold jewelry. In addition to this, many Black Friday deals stay active through Cyber Monday and a lot of the holiday shopping season.

Costco Presidents Day Cyber Event Sale

Costco holds one of the biggest online Presidents Day sales, with significant savings on appliances and electronics, making this sort of the unofficial annual Costco appliance sale. It’s a great chance to get $100 to $300 off appliances like refrigerators or stuff like sofas using a Costco coupon.

Costco July 4th Sale

Although Costco's warehouses close on the Fourth of July, fireworks happen online, where you can find exclusive one-day offers. Costco mixes up these offers every year, but the Costco July 4th Sale has in past years been the best time to get Michelin tires on sale.

Tips to Save More at Costco

If you love saving on everything from snacks to big-ticket items for the household, you know how easy getting a great Costco deal can be. Using one of our verified Costco coupons is the fastest and easiest way to save, but there are more ways to save for those willing to go a little further.

Shop Costco Warehouse Savings

Costco's Warehouse Savings page gives you access to the lowest prices possible on select merchandise, with warehouse prices extending to online orders in most cases. Costco monthly sales include $3 to $14 off apparel and socks for the whole family, $250 to $1,100 off washer/dryer sets, $3 to $30 off snacks and kitchen ingredients, $4 to $30 off self-care items and electronic toothbrushes, and much more.

Shop "While Supplies Last"

The Costco "While Supplies Last" page has special offers on limited inventory items, which are items only available until they sell out. Customers can shop for stuff like appliances, electronics, clothing, home goods, and seasonal items until the stock runs out. Recent markdowns include women's linen dresses, backyard water slides, Zwilling power blenders, and a six-piece outdoor patio set.

Download the Costco App

The free Costco app lets you snap up limited-time deals and coupons before you shop to find the best Costco sales this week. The app features first access to the steep markdowns on "While Supplies Last" items and alerts for upcoming Costco sales.

Upgrade to Executive Membership

Costco Executive Membership often more than pays for itself for the average Costco devotee because you get an annual 2% reward on up to $1,250 in eligible purchases. Plus, Executive Members get a $10 monthly credit on same-day Costo.com orders or Costco Instacart orders over $150.

Executive members also get exclusive Costco car rental discounts and Costco services discounts for things like travel and insurance. Costco Executive Membership also comes with exclusive in-store shopping from 9 a.m. to 10 a.m. on Monday, Saturday, and Sunday.

Apply for the Costco Anywhere Visa® Card

Anyone who applies and qualifies for the Costco Visa® credit card when enrolling as a new Costco Executive Member receives a $50 Costco Digital Shop Card.

Enroll in Automatic Renewal for Your Annual Membership

While Costco doesn't offer student or military discounts, it does have a special Costco membership deal for qualifying members who sign up for Executive or Gold Star memberships. Students and qualifying heroes (military, healthcare workers, teachers and faculty, first responders, and government employees) get a $60 Digital Costco Shop Card for enrolling in Executive auto-renewal or a $40 Digital Costco Shop Card for Gold Star auto-renewal.
