Last Quarter (Q3 Fiscal 2026)
Earnings Per Share (EPS): $4.93 reported versus $4.94 expected
Total Revenue: $70.53 billion, beating the $70.12 billion estimate
Sales Growth: Same-store sales grew 6.6%, and digital e-commerce sales jumped 20.4%
The 3.5 billion dollar increase in warehouse revenue quarterly from Q3 25 to Q3 26 is a pretty strong indicator that all Costcos will be Spirit Halloween stores any day now.

The Winix C610 is a compact air purifier that does a solid job clearing smoke, odors, and other indoor air, with auto mode reacting to VOCs and a filter that can last a long time. It can move a lot of air, especially on higher settings, and Wi Fi scheduling lets it run hard while you are away. The main drawback is noise, since turbo is very loud and some units develop squeaking or bearing problems over time. Filter sourcing also looks less convenient than on the larger C909, which uses easier to find standard A filters.
The C610 can move a lot of air when running at higher settings.
The purifier can make indoor air more manageable during smoke or bad air periods.
Auto mode can ramp the fan when VOCs are detected, which helps during chemical exposure.
Wi‑Fi programming can run Turbo briefly while away and then return to auto to reduce constant noise.
The fan bearings can fail quickly and produce an annoying whining noise.
Turbo mode can be extremely loud, making it hard to run in the same room.
Some units can squeak or develop humming on low, which can prevent using auto mode.
Filter sourcing and airflow on lower settings can be less favorable than the C909, with air movement mainly on turbo.

These too? I have 5 of the box shaped Winix and 1 of them has lasted a long time no issues, one makes only a little noise, one is loud, and two scream 😂 I was hoping the cylinder style would hold up better. I saw that people do the fan bearings with soldering just haven't got around to trying that.
Also the flow rates of the C610 is weird that until you put it to the highest level, it doesn't much that much air, on the lower settings. The C909 moves a lot more air (granted bigger) at level 2 and 3 compared to the C610 which I found only moved air on the turbo setting. That said, this is $100, but I ended up returning the one I had for the C909 and have zero regrets paying the extra money upfront given filters over the lifetime would be cheaper on the C909.
I've ordered 4 total now refurbished from Winix directly and they all appear to be brand new.

For Walmart, most recent quarterly report was $177.8 billion with $117.2B of that from Walmart's US stores, $35.1B from international Walmarts, and a mere $23.4B from Sam's.
But you have to keep in mind that Costco only has about 900 stores total, where Walmart has nearly 11,000 with about 4,500 of those being in the US, 5,800 international stores and 600 Sam's Club stores.
That said it's pretty impressive that annually Costco does about 40% of the Walmart's revenue while having just 8.5% of the number of stores.
Got astounded by the stated 5800 int stores. Like when how? quick search yielded that most of them are Mexico and are under a different name, they just bought out a chain there, not really Walmart
The noise at turbo speed (level 4) on the 610 is so annoying that you literally have to yell to speak to someone.

I added an additional carbon filtration to mine with loose activated carbon pellets in a holder just below the fan (similar to this, but my own design I haven't uploaded yet https://www.printables.
