13 Costco Bulk Buys Under $15 That Are Worth Every Penny This July

We earn commissions for transactions made through links in this post. Here's more on how we make money.

July has a way of turning the kitchen into a revolving door. Kids are home, cold drinks disappear quickly, and an ordinary weekend can suddenly involve feeding six extra people. The right Costco package can cover several meals or snack breaks without pushing your receipt into uncomfortable territory.

The useful buys are not always the biggest packages in the warehouse. They are the ones you can finish, freeze, or divide before anything goes to waste. Prices are accurate at the time of publishing but may vary by warehouse, delivery ZIP code, or availability.

Kirkland Signature rotisserie chicken

A cooked chicken for $5.66 takes care of dinner without heating the oven on a hot July evening. Serve it with salad or corn the first night, then use what is left for sandwiches, quesadillas, chicken salad, or soup. That is more mileage than most prepared meals offer at this price.

The value depends on using more than the easy-to-reach breast meat. Pull the entire chicken while it is still warm, refrigerate what you need, and freeze any portion you will not eat within a few days. The carcass can also make broth, though nobody is required to turn a bargain chicken into a weekend project.

Kirkland Signature cage-free eggs

This package contains two dozen large Grade AA cage-free eggs for $6, or about 25 cents per egg. Eggs can cover breakfast, add protein to a quick lunch, or turn leftover vegetables into a frittata before they expire.

A two-dozen carton makes sense for families, regular bakers, or anyone who meal-preps breakfast sandwiches. Smaller households should check the expiration date and be honest about how often they cook. This is a good price only when the last six eggs do not spend a month quietly judging you from the back of the refrigerator.

Kirkland Signature butter croissants

The bakery’s all-butter croissants cost $6.80 for a dozen, which comes to roughly 57 cents each. Split them for sandwiches, serve them with eggs and fruit, or warm one for a breakfast that feels less bleak than another piece of dry toast.





Twelve croissants can be too many if you live alone, but they freeze well. Slice them before freezing so you can toast one straight from the freezer instead of thawing the whole package. They are also useful for feeding overnight guests or putting together a brunch without paying bakery prices by the piece.

Kirkland Signature organic tortilla chips

A 40-ounce bag of organic white and yellow corn tortilla chips is $6.80. That works out to about 17 cents per ounce, with enough chips for several taco nights, packed lunches, or a backyard gathering. The chips are also certified gluten-free and non-GMO.

The main risk is freshness, not cost. Close the bag tightly or divide it into sealed containers as soon as you get home. This size is useful when several people snack from it or when you are hosting. A small household that eats chips twice a month may save more by buying a smaller bag that does not end as expensive crumbs.

Kirkland Signature organic hummus cups

Twenty individual 2.5-ounce hummus cups cost $8.96, or about 45 cents per serving. Pair one with vegetables, crackers, or pita for a quick snack that is already portioned and ready to pack.

The cups solve a common bulk-buy problem because you are not repeatedly opening one large tub and hoping it stays fresh. They make particular sense for work lunches, summer camp bags, or households where one person likes hummus and everyone else treats it with suspicion. Check that you have enough refrigerator room before buying, since the convenience comes in 20 small containers.

Kirkland Signature organic chunky guacamole cups

At $14.74 for 16 individual cups, each serving costs about 92 cents. The sealed portions are easier to manage than a large container of guacamole, which can turn brown between dinner and the moment you finally remember it exists.

Use the cups for toast, tacos, burrito bowls, sandwiches, or packed lunches. They are especially practical for one- and two-person households because you can open only what you need. The price is close to the $15 ceiling, but the reduced waste helps justify it. This is less useful for a large party, where one full-size tub would create less packaging and require less lid peeling.





Kirkland Signature soft and chewy granola bars

A box of 64 chocolate chip granola bars costs $12.13, bringing each bar to about 19 cents. They are made with whole rolled oats and contain no artificial colors or flavors.

This is the kind of bulk package that can lower the cost of packed snacks without creating extra work. Keep some at home, some at work, and a few in a travel bag for long July drives. The bars are small, so they are better as a snack than a full breakfast. Households that do not regularly pack lunches should also consider whether 64 bars will disappear before everyone gets tired of them.

Kirkland Signature mini chocolate chip cookies

The 60-count tub of mini chocolate chip cookies is $11.34, or roughly 19 cents per cookie. Their smaller size makes them easier to portion for lunches, picnics, and children’s snacks than oversized bakery cookies.

They also give you an inexpensive dessert to put out when friends stop by, without paying for individually wrapped snack packs. Move some into an airtight container and freeze the rest if your household will not finish the tub promptly. This is still a treat rather than a pantry staple, but it earns its place when you need to serve a group and do not want to spend Saturday baking in July heat.

Busseto salami and provolone snack packs

Eight individual three-ounce packs of bite-size salami and provolone cost $14.74, which is about $1.84 per pack. Each package is ready to grab for work, errands, road trips, or a quick lunch with fruit and crackers.

The total price is higher than making your own portions from a block of cheese and a package of salami. What you are paying for is convenience without convenience-store pricing every time hunger hits. These make sense for people who routinely buy snacks while away from home. If you have ten minutes to portion food on Sunday, the do-it-yourself route will still be cheaper.

Kirkland Signature purified drinking water

A 40-bottle case of 16.9-ounce purified water is $4.53, or about 11 cents per bottle. That is useful for summer sports, emergency supplies, outdoor work, and events where reusable bottles are not practical.





For everyday drinking at home, refilling a bottle is cheaper and creates less waste. This case earns its shelf space when it replaces single bottles bought at gas stations or concession stands. Store it somewhere cool, and make sure you can comfortably lift and carry it. A bargain becomes less impressive when getting it out of the trunk requires a physical therapist.

Fresh strawberries

A two-pound clamshell of strawberries is $6.23, or about $3.12 per pound. During hot weather, they can cover breakfasts, snacks, smoothies, and simple desserts without requiring much preparation beyond washing and removing the tops.

The value disappears quickly if half the berries soften in the refrigerator. Check the package carefully, wash only what you are ready to eat, and freeze extras before they turn. This size works best for families or regular smoothie drinkers. Smaller households can still make it worthwhile by freezing a tray of berries for later instead of waiting for the fuzzy ones to make the decision.

Kirkland Signature dishwasher detergent pacs

A tub of 115 dishwasher detergent pacs costs $13.61. That comes to roughly 12 cents per load, and Costco says the lemon-citrus pacs do not require a prewash.

This is a straightforward stock-up for households that run the dishwasher several times a week. The container lasts long enough to reduce emergency trips for a small box at a higher per-load cost. Keep it dry and away from children, since moisture can cause the pacs to stick together. People who prefer unscented detergent should skip this one, because a low unit price does not make a fragrance less noticeable.

Dixie Ultra paper bowls

The package includes 135 microwave-safe, cut-resistant 20-ounce bowls for $14.52, or about 11 cents per bowl. They are deep enough for cereal, chili, ice cream, pasta salad, and other foods that make flimsy plates a poor life choice.

Disposable bowls are not the cheapest choice for ordinary meals, but the bulk package can pay off during parties, camping trips, renovations, or periods when washing another dish feels unreasonable. They are also useful for large family gatherings where the host would otherwise buy several small packs. Make sure you have dry storage for all 135, because paper goods are only convenient when they are not occupying half the kitchen table.
