Costco Must-Haves in September: Food Deals to Stock Up On

Each month, Costco comes out with a coupon book full of exciting deals, and this month’s Costco ad is no different. You really save more when you shop their sales ad, which is basically their monthly coupon book.

If you’re wondering about the best grocery deals at Costco in September, I went to my local warehouse and compiled a list for you. These savings are only valid through September 22, so make sure to shop before then if any of these finds caught your eye.

1. Country Archer Grass Fed Beef Sticks ($12.99)

If you’re looking for an effortless and delicious way to add protein to your diet, try these mini grass-fed beef sticks. Each stick contains 4g of protein, zero sugar, and just 50 calories. One bag comes with 28 individually packaged sticks, which are currently on sale for $3.80 less than the usual price.

2. Nature Valley Sweet & Salty Bars ($10.99)

These Sweet & Salty granola bars from Nature Valley are chewy, creamy, and packed with peanuts. These boxes are huge, and the picture doesn’t do it justice – there are 48 bars in each box. They usually go for $15.99, but they’re on sale this month for $10.99. That means each bar costs just around a quarter.

3. Caribe Queso Panela ($8.99)

Queso panela is a fresh cheese made of pasteurized cow’s milk, and you can grab a whole 3-pound wheel of it for $8.99 this month. It’s mild and keeps its shape very well in heat, similar to paneer. Costco’s regular price for this cheese wheel is $11.99.

4. Mars Mixed Singles Variety ($20.79)

Halloween isn’t too far away, so it’s time to stock up on candy for yourself or trick-or-treaters. I always thought only the rich could afford to give out the legendary “full-sized” candy bars, but they cost less than a dollar apiece at Costco. You can grab a 30-count of full-sized Snickers, Twix, Milky Way, Peanut M&Ms, and regular M&Ms for $20.79, rather than the usual $27.99 price tag.

5. Pulmuone Teriyaki Stir-Fry Udon ($5.59)

Getting a bowl of teriyaki udon for just $5.59 already sounds like a great deal, but when you realize each bag comes with four noodle, seasoning, and topping packets, it’s an unbelievable deal!

Keep these noodles refrigerated, and simply microwave them when you’re ready to eat. Udon is my favorite type of noodle, so I picked up a pack of these as soon as I saw them in the refrigerated section.

6. Blount Creamy Tomato Soup ($6.99)

You can get a two-pack of 24-ounce Creamy Tomato Soup for $6.99 this month, which is a $3 discount from the regular price. This is my go-to soup at Costco, so I had to stock up on my recent visit. This tomato soup is always fresh and has the perfect balance between tomato, basil, and creaminess.

7. Rojo’s Street Corn Dip ($6.59)

Rojo’s Street Corn Dip is another of my Costco favorites, and it’s on sale right now for $6.59. This dip is hefty – 2 pounds, to be exact – so it’ll last you quite a while. Inside, you’ll find a creamy dip made with corn, green chiles, cheddar cheese, and cotija cheese. It can be served hot or cold, but I usually eat it cold with some veggies and tortilla chips.

8. General Mills Honey Nut Cheerios ($6.19)

Honey Nut Cheerios seems to be one of the most popular cereals, so I think this deal will be a hit. You can get two huge cereal boxes for $6.19 instead of the usual $8.99 price. Even if you eat a bowl of Cheerios every morning, it’ll probably take at least a month or two to get through these boxes.

9. Fritos Scoops! Corn Chips ($4.89)

Fritos Scoops have the same classic, salty taste of a corn chip but are shaped like a scoop, making them perfect for picking up guac, salsa, or the dip of your choice. This big bag is on sale at Costco for $4.89 instead of the regular $7.39 price tag.

I’m a huge fan of Fritos, so I usually buy two bags when they go on sale, and the two of them last me a few months. Just be sure to use a clip or piece of tape to seal the bag; otherwise, these will get stale pretty easily.

10. Good Foods Organic Chunky Guacamole ($6.99)

Avocados are notoriously pricy, so getting premade guacamole instead of avocados can be a cost and time-saving decision. This organic chunky guac from Good Foods features tomato, red onion, and garlic and has no preservatives or added sugars. This is as close to fresh as you can get without being homemade. There are three containers per pack, which costs $6.99, and each container holds 10 oz of guacamole. These are great to pick up for a party.

11. Don Miguel Chicken Mini Tacos ($9.49)

These mini tacos are currently on sale for $9.49. They’re seasoned with chipotle chile and wrapped in a crispy corn tortilla. Each package comes with 50 mini tacos that can be ready after a quick trip to the oven or air fryer. These are perfect for an end-of-summer (or beginning-of-fall) get-together, especially when paired with the guac I mentioned above!

12. Del Real Pork Carnitas ($13.99)

These Slow-Cooked Pork Carnitas are fully cooked and ready to serve once warmed up. Serve the carnitas in taco shells, a burrito, a bowl, or whichever you like. Carnitas are traditionally served with cilantro, salsa, and refried beans, so be sure to add these ingredients for the full experience. This product may seem on the pricier side, but each package contains 2.5 pounds of meat, so you’re getting a fair amount of bang for your buck.

13. Frankly Fresh Chicken Burrito Bowl ($10.59)

The easiest burrito bowl of all time is available in Costco’s refrigerated section this month for $10.59 per 3 bowls. These are fully cooked and only need to be heated up before they’re ready to serve. Each bowl comes with seasoned chicken breast, a blend of brown and white rice, black beans, corn, roasted salsa, and jack and cheddar cheeses.
