Don't Miss Out: The Best Costco Buys To Grab Now Before Summer Ends

Bush's organic black beans are rich in fiber and protein. They’re also versatile enough for multiple dinners, including soups, stir-fries and more. You get eight 15-ounce cans, making each one cost about $1.40. Even better than the low everyday price is that your purchase will last you a long time.
Kirkland Signature Rotisserie Chicken
Price: $5.66
You can never go wrong with Costco’s rotisserie chicken, as many frugal shoppers will attest.
"There is one Costco product that I nearly always buy and that is their $4.99 rotisserie chicken,” said Clay Cary, Senior Trends Analyst and finance expert at CouponFollow.
One rotisserie chicken can easily last several meals, especially if you’re one person. You can use it for tacos, soups, pastas, salads or even sandwiches.
Ritika's Organic Cilantro & Lime Rice
Price: $12.02
Another key dinner staple is rice. You can use it across multiple dishes, including soups. Ritika's organic cilantro & lime rice is also a great side dish.
Don’t be thrown off by the bulk price tag. You get six 8.8-ounce bags. The rice itself is gluten- and dairy-free, as well as vegan.
Bibigo Chicken and Cilantro Mini Wontons
Price: $8.50
These mini chicken and cilantro wontons aren’t just for the budget-conscious shopper. They’re also convenient when you don’t have a lot of time to cook, or when you’re running low on dinner ingredients.
With this option, you get three pounds’ worth of wontons. Serve them alongside rice or frozen veggies from Costco, and you’ve got yourself multiple inexpensive meals.
Kirkland Signature Uncured Black Forest Ham
Price: $11.34
Sandwiches are great for lunch and dinner, especially during hotter months. This 28-ounce package of uncured Black Forest ham could last you an entire week’s worth of dinners. Pair it with some inexpensive bread, cheese and fresh veggies from Costco and you won’t have to cook for a while.
Kirkland Signature Organic Broccoli Florets

Plus, frozen vegetables like these broccoli florets won’t go bad anytime soon. You get four, one-pound packages, so you can use one per dinner.

Kirkland Signature Extra Crispy French Fries
Price: $7.93
For another easy side dish, try out Kirkland Signature Extra Crispy French Fries. They’re easy to cook in the air fryer or on the stove. They also pair well with chicken or beef, as well as fresh or frozen vegetables.
You get five pounds in total, so there’s no need to use them all at once. Use a third of the bag (or less) per meal and you’ve got enough for two more dinners later.
Samyang Buldak Ramen Carbonara, Spicy Chicken
Price: $11.11
If you like ramen, you’ll be set for a while with this six-pack of spicy chicken ramen. Each one makes for its own dinner, but you might want to spruce it up. Add a soft-boiled egg or some bok choy for more nutritional value.
Kirkland Signature Eggs
