Let’s dive into the best under-$5 staples Costco has to offer—you might be surprised by what’s worth grabbing on your next trip.
1. Two Artisan Baguettes – $4.99
French bakery quality without the Parisian price tag! Each package contains two substantial baguettes with that perfect contrast between crackling crust and airy interior.
Warm them for 5-10 minutes in a 350°F oven to experience bread nirvana. They transform simple ingredients into impressive meals – try them with soup, as garlic bread, or as the foundation for bruschetta appetizers.
Don’t worry if you can’t finish both loaves immediately. Slice the second baguette, freeze it, then toast pieces directly from frozen whenever bread cravings strike.
2. Blackberries – $3.85
Sweet, tart, and bursting with antioxidants, Costco’s blackberry containers hold twice the amount you’d find at regular grocery stores. The berries arrive plump and fresh, often organic depending on your location.
Snack on them straight from the container or transform your morning routine by adding them to oatmeal, yogurt, or smoothies. They freeze beautifully too!
Unlike other berries that spoil quickly, blackberries typically last 5-7 days in your fridge when stored properly. That’s serious fruit value for under five dollars.
3. Baby Spinach – $4.29
That enormous plastic container of tender green leaves might be the best vegetable deal in America. Costco’s baby spinach comes pre-washed and ready to use, saving precious meal prep minutes.
The mild flavor makes it incredibly versatile. Throw handfuls into morning smoothies (you won’t taste it!), use it as salad base, or wilt it into pasta sauces and soups for an instant nutrition boost.
Storage hack: Place a paper towel inside the container to absorb excess moisture. This simple trick extends freshness by several days, ensuring you get through the entire package.
4. Rotisserie Chicken – $4.99
The legendary bird that launched a thousand meals! Weighing in at a hefty three pounds, Costco’s rotisserie chicken delivers incredible value that no grocery competitor can match.
Juicy, perfectly seasoned, and ready to eat, this protein powerhouse transforms into countless quick meals. Shred it for tacos, slice it for sandwiches, or dice it for soups and salads.
Pro tip: Buy two and freeze the extra meat in portion-sized containers. The bones make fantastic homemade stock that puts store-bought versions to shame.
5. Sea Salt – $3.97
Kitchen essentials don’t get more fundamental than salt, and Costco’s Kirkland Signature sea salt delivers exceptional quality at a fraction of specialty store prices. The generously-sized grinder will season hundreds of meals before needing replacement.
The pure, clean taste elevates everything from scrambled eggs to chocolate chip cookies. Many professional chefs secretly stock this exact product in their restaurant kitchens.
Beyond cooking, it makes an excellent addition to homemade body scrubs or bath soaks. For under four dollars, you’re getting a pantry staple that will last months, possibly years.
6. Deli Hamburger Buns – $4.20
Forget those flimsy, air-filled buns from the grocery store! Costco’s bakery buns have a brioche-like richness and pillowy texture that transforms ordinary burgers into restaurant-worthy creations.
Each pack contains 12 substantial buns that stay fresh for days longer than typical bread products. They have just enough sweetness to complement savory fillings without overpowering them.
Beyond burgers, these versatile buns make excellent breakfast sandwiches or dinner rolls. Split them, butter both sides, and toast them on a griddle for an elevated experience that’ll ruin regular buns for you forever.
7. Pita Flat Bread – $4.67
Remember the last time you paid $8-10 for a single restaurant flatbread? Costco’s package includes six substantial pitas for under five dollars, each one perfectly pliable yet sturdy enough for hearty fillings.
These versatile rounds work breakfast through dinner. Toast them for quick personal pizzas, stuff with falafel for lunch, or tear into pieces for dipping in hummus as an afternoon snack.
Unlike many store-bought pitas that crack when folded, these remain soft and flexible for days after opening. Store them in the freezer with parchment paper between each piece for grab-and-go convenience.
8. Sweet Potatoes – $3.79
Costco’s sweet potato bags deliver serious value – typically 6-8 large tubers for under four bucks. These nutrient-packed vegetables have an impressive shelf life, often lasting weeks when stored properly in a cool, dark place.
Their natural sweetness intensifies when roasted, creating caramelized edges that taste almost dessert-like. Cut them into cubes for meal prep, slice them into fries, or bake them whole for a simple side dish.
Bonus: Sweet potatoes contain more fiber than regular potatoes and are loaded with vitamin A. Even picky eaters tend to enjoy their naturally sweet flavor profile.
9. Bananas – $2.48
At just $0.59 per pound, Costco’s banana bunches are quite possibly the most economical fresh fruit available anywhere. Each bunch typically contains 7-9 large bananas – perfect for families or meal preppers.
The ripening process seems perfectly timed too. Buy them slightly green, and they’ll gradually ripen throughout the week, ensuring you always have perfectly yellow fruit ready to eat.
Don’t worry about extras going brown! Peel and freeze overripe bananas for smoothies or baking projects. Some Costco shoppers even report their bananas lasting longer than those from traditional grocery stores.
10. Boom Chicka Pop Popcorn – $4.67
Hidden in Costco’s snack aisles, this 6-ounce bag of kettle corn strikes the perfect balance between salty and sweet. Made with simple ingredients you can actually pronounce, it satisfies munchies without the guilt of typical processed snacks.
The resealable bag helps maintain freshness, though good luck having any left to save! With just 140 calories per serving, it’s a lighter alternative to chips or cookies.
Parents love this for lunchboxes and after-school snacks. Movie nights, road trips, or afternoon energy slumps – this popcorn handles them all while keeping your wallet and waistline happy.
