Is walking the aisles of Costco considered fun to you? Do you catch a thrill staring at your latest haul, knowing exactly how much money you saved? Love seeing a freezer stocked with Kirkland products?
You have come to the right place! Welcome to Warehouse Wanderer.
This wholesale club is magical, but it can sometimes be tricky to navigate. Despite Costco having an extensive vetting process, buying in bulk means a bigger upfront investment. You want to know the math makes sense—and that you will actually enjoy the product—before purchasing.
When you buy something, you need to know how to use it. Because letting a bulk item sit in your fridge or freezer until it expires isn’t a deal; it’s a budget trap.
Here, you will get the hard price-per-ounce math on the latest Costco deals, data-backed reviews on which Kirkland products are actually worth buying (and how to use them), and strategic ways to store bulk purchases so zero dollars go to waste.
Let’s do the math and make the most of your Costco membership!
Here, you will learn about the latest Costco deals, which Kirkland products are worth buying (and how to use them), and how to store bulk purchases.

Does Kerry Irish butter still have pfas in the wrapper?
I don’t believe so. The last I heard of that was back in 2023 and rectified. Certain states in the US ban them.
Hi there,
My name is Sophia, and I am the PR Rep for ZOA Energy, which is featured in your most recent article entitled “Complete List of Costco Food Sales This Week: October 15, 2025”. I am reaching out because there seems to be a typo with ZOA Energy listing, which reads “Zoa Energy Zero Sugar Drink was $21.99 now $14.99,” while the correct pricing should be that is was originally $25.99 and is now $18.99. This reflects a 28% discount of $7 off.
Can you update your article to reflect the correct information? If there is anything you might need from us to do so, please let me know.
Thanks so much,
Sophia
Hey Sophia,
Appreciate your comment.
I got the info from my visit to the warehouse and I just double checked the Costco app and the pricing I have is there as well. Happy to share the screenshots with you. Perhaps that info is wrong?
Help….do you know from what company Costco sourced their frozen Waygu grass fed beef patties? We bought awhile back and loved them. Got down to 2 left and went back to buy more. OH NO!!!!! They don’t carry anymore. What???? They are the best….crazy dumb people. Anyway, can you help?
Thanks!!
Hi Beverly,
Costco is very tight-lipped on their sourcing but this is a seasonal product so you will likely find it back in the warehouse come May.
