I’ve always looked for ways to save money on groceries without sacrificing quality or convenience. Buying in bulk at Costco seemed like a good option, but I wasn’t sure if it would actually make a difference in my budget. After trying a few key items, I noticed real savings that added up over time.
By focusing on a handful of smart bulk buys, I managed to cut my grocery spending by $150. It wasn’t about buying everything in giant quantities but picking the right products that last and offer great value. This article shares which Costco items made the biggest impact on my wallet.
Kirkland Signature Organic Extra Virgin Olive Oil
I started buying Kirkland Signature Organic Extra Virgin Olive Oil because the quality is solid for the price. The 2-liter bottle lasts me a long time, and it’s USDA organic, which gives me peace of mind.
It’s great for everyday cooking and salads. Plus, Costco’s price makes it easy to stock up without feeling like I’m overspending. I’ve found it’s a smart choice if you want decent olive oil without breaking the bank.

Kirkland Signature Frozen Wild Blueberries
I love keeping a big bag of Kirkland Signature Frozen Wild Blueberries on hand. They’re super convenient for smoothies or baking and taste fresh because they’re quickly frozen after harvest.
Buying in bulk saves me money and reduces trips to the store. Plus, the 5-pound bag lasts a long time in the freezer without losing quality. If you want to grab some, Costco offers fast delivery options too. You can check out more details about Kirkland Signature Wild Blueberries delivery here.
Nature Valley Granola Bars Multipack
I always keep a multipack of Nature Valley Granola Bars on hand. The oats ’n honey flavor is my go-to for quick snacks or a simple breakfast.
Buying the 49-count pack from Costco saves me money and trips to the store. These bars are made with whole-grain oats and no artificial flavors, which feels like a healthier option.
They’re easy to grab when I’m rushing out the door or need something at work. You can find them with fast delivery if needed too.
Kirkland Signature Rotisserie Chicken
I always grab the Kirkland Signature Rotisserie Chicken when I shop at Costco. It’s super affordable, usually around $5, and already cooked, which saves me so much time.
The flavor is solid, and it’s big enough to stretch across a couple of meals. Buying a few at once lets me stock up without breaking the bank.

Hefty Slider Storage Bags Bulk Pack
I picked up a bulk pack of Hefty Slider Storage Bags from Costco to help with organizing my fridge and snacks. They come in gallon and jumbo sizes, which is perfect for everything from leftovers to craft supplies.
The slider seal is easy to use and really keeps things airtight. Buying in bulk means I’m stocked for months and I spend way less replacing single packs. You can check out the Hefty Slider Bags at Walmart for options.
