Kirkland Signature Beef Hot Dogs
Price: $16.29
You get three packages of 12 bun-length beef hot dogs each for around $16, making it one of the lowest per-unit prices you'll find on a quality beef frank. Kirkland Signature Beef Hot Dogs are a cookout staple and with grilling season in full swing, stocking the freezer now means you're covered through Labor Day without paying inflated prices at the grocery store.
Kirkland Signature Frozen Chicken Breasts
Price: $19.99
At around $3 per pound, Kirkland Signature individually frozen chicken breasts are a summer grill staple that belongs in every freezer. The 6.5-pound bag keeps you ready for quick weeknight dinners, meal prep or last-minute cookouts. Buying in bulk now hedges against the protein price increases that tend to creep in through late summer.
Sun Bum Original SPF 50 Sunscreen
Price: $23.99
This multipack gives you two spray bottles of SPF 50 sport sunscreen — enough to cover the whole family for multiple beach days. Sun Bum SPF 50 Moisturizing Sunscreen Spray sells fast once temperatures peak and Costco's warehouse price saves you significantly compared to buying individual bottles at a drugstore. Stock up while the summer is still young.
Off! Deep Woods Dry Insect Repellent Set
Price: $20.99
Mosquitoes and bugs don't take summer off, and neither should your repellent supply. This Costco set includes two 7.5-ounce cans and one 2.5-ounce can of Off! Deep Woods Dry Insect Repellent, giving you protection for camping trips, evening patios and outdoor activities all season long. Buying the multipack here beats convenience store pricing by a wide margin.
Dixie Ultra 10-1/16" Paper Plates
Price: $23.99
With 186 heavy-duty dinner plates in a single pack, you're set for an entire summer of cookouts without the dishwashing. Dixie Ultra paper plates are thick enough to hold saucy ribs and loaded burgers without buckling, making them a practical buy for anyone hosting regularly. Disposable tableware tends to see price bumps ahead of peak grilling season, so filling up now is a smart move.
Gatorade Thirst Quencher Core Variety Pack
Price: $15.69
A 28-pack of 12-ounce Gatorade Thirst Quencher bottles in a variety of flavors is a must-have for hot-weather hydration. At just under $16 for more than two dozen bottles, the per-bottle cost is well below what you'd pay at a gas station or grocery store mid-summer. Keep a case in the fridge for kids, workouts or anyone working outside in the heat.
Frito-Lay Classic Mix Variety Pack
Price: $18.49
Fifty-four individual bags of fan-favorite Frito-Lay chips — including Lay's, Doritos, Cheetos and Fritos — make this Classic Mix variety pack ideal for parties, picnics and grab-and-go snacking all summer long. The price breaks down to 34 cents per bag, which is significantly less than you'd spend buying multipacks at a regular grocery store. It's the kind of bulk buy that pays for itself the first time you host.
Welch's Fruit Snacks
Price: $12.19
Ninety pouches of mixed-fruit snacks for around $12 is a deal worth grabbing before school's out and demand spikes. Welch's Fruit Snacks are a lunchbox and pool-bag staple that the whole family reaches for and the Costco bulk price keeps you stocked through the summer without repeated grocery runs. At about 14 cents per pouch, it's hard to beat.
Heinz Classic Variety Pack
Price: $13.99
This four-bottle Heinz bundle — two 31-ounce ketchup bottles, one 28-ounce yellow mustard and one 34.2-ounce barbecue sauce — is everything you need to condiment a summer's worth of cookouts in one purchase. The Heinz Classic Variety Pack is an easy win at Costco, priced lower per ounce than buying these staples individually at most grocery stores. Stock it in the pantry now and forget about condiment restocking for a long while.
Kirkland Signature Chinet Red Cups
Price: $12.99
Two hundred and forty 18-ounce red cups for around $10 is the math every backyard party host likes to calculate. Kirkland Signature Chinet Red Cups are heavy-duty enough to handle ice, drinks and outdoor summer use without cracking and buying 240 at once means you won't run short mid-party. At just over 4 cents per cup, it's one of the best value buys in the store.
Kirkland Signature Premium Blend BBQ Hardwood Pellets
Price: $17.99
A 40-pound bag of Kirkland Signature Premium Blend BBQ Hardwood Pellets gives you a whole lot of smoking power for the rest of summer. It's a classic seasonal item that sees price increases and supply shortages as summer heats up, so buying a heavy supply now at Costco's warehouse price means you're ready for every cookout through the end of the season without scrambling.
