Whether you’re bulking up or cooling down, Costco is ready for you this July and August with 11 fantastic deals. 

Orgain Organic Protein + Superfoods Protein Powder 

$8 off each 2.7- or 2.64-pound tub

Adding protein to a morning or post-workout smoothie is a great way to maximize your protein intake, especially if you’re strength-training or needing a boost before you head out the door. This Orgain Organic Protein + Superfoods Protein Powder only has a gram of sugar, but it’s packed with probiotics and a whopping 8 grams of fiber. The protein itself is all plant-based and vegan, so it’s more versatile for people who prefer plant-based protein.

Perfect Bar Organic Protein Bars 

$6 off each 12-count pack

These gluten-free, organic protein bars are massively discounted–$6 off a box of 12. With 15 to 17 grams of protein per bar, Perfect Bars are great for hikes, picnics or busy mornings. The peanut butter and peanut chocolate flavors can help satisfy your sweet tooth while still providing a boost of energy.  

Premier Protein Shakes 

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

Premier shakes pack 30 grams of protein per bottle and just 1 gram of sugar per shake. They’re a good source of gluten-free nutrients and protein, which can make them helpful for days when you forget to snag breakfast or need some extra protein to power through a workout. Plus, this deal means it’s a good time to try Premier shakes out if you haven’t already.

Kirkland Signature Coffee Pods 

$6 off each 120-count box

Coffee pods make morning (or afternoon) coffee a snap. The Kirkland Signature Coffee Pods are made with organic, fair trade certified, organic, 100% Arabica coffee and work in Keurig machines. This well-reviewed coffee pod option is $6 off a 120-count pack, which helps cut down on costs without sacrificing flavor. 

Brita Pitcher Filters 

$12.50 off each 10-count package or a pitcher with two filters

Fresh, filtered water is a must while the weather is still sweltering. Water filtered with a Brita Filter reduces copper, mercury and cadmium and removes many tastes and odors from tap water. It also reduces sediment and water hardness. The filters, when bought separately, fit all Brita pitchers and if you’re new to Brita, the pitcher with two filters is available and on sale as well. 

Reynolds Wrap Heavy Duty Aluminum Foil 

$5.50 off each 2-pack of 150-foot rolls

Grilling season, the best season, is made easier with aluminum foil for helping contain veggies and lock in flavorful marinades on meat and other yummy grilled meals. But aluminum foil is also necessary year round, and stocking up now can set you up for easy sheet-pan meal prep well into next season.

Maison Perrier Sparkling Water 

$6 off each 24-count box of 16.9-ounce bottles

Sparkling water like Maison Perrier sparkling water has health benefits, but the biggest one is that it can help you stay hydrated without added sweetener or other additives, unlike juice or soda. If you don’t love the taste of flat water, Perrier can feel fizzy and fancy, encouraging you to drink more. These resealable bottles are great when you’re on-the-go, and a pack of 24 is currently $6 off, so staying hydrated has never been easier. 

Bobo’s PB&J Oat Sandwich Bars 

$5 off each 20-count pack

Bobo’s PB&J Oat Sandwich Bars are a lunchbox staple, but they’re also great for camp snacks, picnic treats or mid-afternoon slump pick-me-ups. These vegan and gluten-free bars have 17 grams of whole grains per serving. This sale is perfectly timed to make snack-time easier than ever. 

SkinnyPop Organic Popcorn 

$2.30 off each 14-ounce bag

Since SkinnyPop is gluten-, dairy- and trans fat-free, this kosher snack works for most crowds, no matter their dietary restrictions. It’s great for movie night, a quick bite at your desk or as an after-school snack. Since it tends to go quickly, you might even want to grab two bags while this deal is running. 

Siete Grain-Free Tortilla Chips 

$2.40 off each 15-ounce bag

Unlike lots of chips, Siete Grain-Free Tortilla Chips are made with cassava flour—one of the healthiest flours—and avocado oil, which makes them both healthier and more accessible to all kinds of folks, as they’re gluten free, paleo and vegan. Enjoy your chips and salsa for less since these 15-ounce bags are over $2 off. 

Chosen Foods Avocado Oil Spray 

$4.20 off each 2-pack of 13.5-ounce bottles

Avocado oil is one of the best oils to cook with because of its health benefits and high smoke point. Avocado oil in a spray makes using avocado oil in your cooking that much easier, and Chosen Foods Avocado Oil Spray is currently over $4 off each 2-pack. This neutral-tasting spray is made from naturally refined 100% avocado oil, so you’re getting a high-quality, versatile product for less.
