The 10 Best Deals to Buy at Costco Right Now

There’s nothing quite like a good Costco run—the thrill of buying a lifetime supply of paper towels, the free samples that somehow turn into a full meal and, of course, the unbeatable deals. But any trip to Costco has the potential to spiral into a spending spree, which means it’s always a good idea to check the sales and put your shopping list together in advance.

This month, from March 5 to March 30, Costco has some serious markdowns on everything from pantry staples to tasty snacks, making it the perfect time to stock up. Whether you’re looking for better breakfasts, healthier snacks or just an excuse to try something new, these are the 10 best deals to grab before they’re gone.

Liquid IV Hydration Multiplier

$8 off each 30-count package

Staying hydrated is essential, but sometimes water alone doesn’t cut it. Whether you’re recovering from a tough workout, fighting off a cold or bouncing back after a night out, Liquid IV helps replenish electrolytes quickly. It’s a must-have for anyone who exercises regularly, spends time in hot weather or just wants to feel a little more refreshed throughout the day—though you should know that it is possible to overdo it on electrolyte drinks. But if you’re a fan of these mix-ins, $8 off means it’s the perfect time to stock up. 

Unreal Dark Chocolate Coconut Minis

$3.30 off each 15.3-ounce package

Anyone who says healthy eating is boring has clearly never tried these. Dark chocolate is loaded with antioxidants and has been linked to heart health, brain function and even better moods. But let’s be honest—you’re probably eating these bite-size treats because they’re delicious. The mix of rich chocolate and chewy coconut makes them taste like an upgraded candy bar, minus the artificial extras.

Heavenly Hunks Organic Oatmeal Dark Chocolate Cookies

$3 off each 22-ounce bag

Speaking of dark chocolate, Heavenly Hunks Organic Oatmeal Dark Chocolate Cookies are the kind of treat that hits the spot every time. With chewy oats and rich dark chocolate chunks, they’re sweet, satisfying and perfect for when you need a little something after dinner. Whether you’re looking for an afternoon snack or the perfect sweet-treat nightcap, these cookies have you covered. And with $3 off, there’s no reason not to try a bag (or two).

BoomChickaPop Kettle Corn

$2.30 off each 25-ounce bag

Salty and sweet is always a winning combo, and BoomChickaPop Kettle Corn delivers every time. Light, crispy and perfectly balanced, it’s the kind of snack that disappears fast—whether you’re settling in for a movie night or just need something to munch on. Plus, popcorn is a whole grain, so it’s a high-fiber, lower-calorie snack option that can help keep you satisfied. And at $2.30 off, now’s the time to stock up.

Chobani Nonfat Greek Yogurt

$5 off each 20-count pack of 5.3-ounce containers

Greek yogurt is a breakfast staple for a reason—it’s packed with protein, probiotics and calcium, making it a solid choice for gut health and overall nutrition. This month’s deal makes it even easier to stock up. For the best option, stick to plain Greek yogurt and add your own toppings, like fruit, nuts or a drizzle of honey. Or, if you’re feeling fancy, throw it into our Fruit & Yogurt Smoothie or use it as a base for this creamy three-ingredient salad dressing.

Suja Immunity Wellness Shots

$4.50 off each box of 10 (2-ounce) shots

Cold season is here, and these little bottles of goodness are here to help. Packed with anti-inflammatory ingredients like turmeric, ginger and echinacea, Suja’s wellness shots are designed to give your immune system a boost. Plus, they even get the thumbs-up from one of our editors, who loves the peppery taste (and the appealing price point). Whether you’re trying to fend off a bug or just want an extra boost, now is the time to stock up while they’re $4.50 off.

No cooking, no mess; just grab one from the fridge and start your day. They’re perfect for busy mornings, post-workout fuel or those days when making breakfast feels like too much effort—we’ve all been there.

Season Sardine Fillets

$3 off each box of six cans

Sardines might not be the first thing you think to grab at Costco, but hear us out. These little fish are packed with protein, omega-3s and calcium, making them one of the most nutrient-dense foods you can buy. If eating them straight from the can isn’t your vibe, try adding them to a pasta like our Lemon-Garlic Sardine Fettuccine or our Spicy Sardine Linguine. Trust us, it’s a game-changer.

Premier Protein Shakes

$6 off each 18-count box of 11-ounce shakes

Getting enough protein doesn’t have to mean spending hours in the kitchen. Premier Protein Shakes pack 30 grams of protein into a smooth, satisfying drink. They’re perfect for busy mornings, post-workout fuel or a quick snack that actually keeps you full. They’re an easy grab-and-go option for anyone looking to up their protein without the extra effort. And at $6 off, now’s the time to stock up.

Kirkland Coffee K-Cups

$6 off each box of 120 pods

If the thought of running out of coffee sends a chill down your spine, now’s the time to stock up.

Now that they’re $6 off, you can avoid a much-dreaded groggy morning by loading up your coffee supply.
