Costco members will ride or die for that warehouse. After the loyalty the $1.50 hot dog combo has shown us, it’s honestly the least they can do. They’ll post their TV deals like proud parents showing off newborns. And now — after Costco sued the Trump administration over billions in tariffs — many of them are ready to swear fealty to the big red-and-blue temple of bulk goods.
Costco’s Doing What Now?

The lawsuit itself is pretty straightforward. Costco filed in the Court of International Trade, arguing that the Trump administration’s tariffs — issued through the International Emergency Economic Powers Act — weren’t legally authorized. Since Trump was the first president ever to use IEEPA to impose import duties, lower courts have been raising eyebrows for years, and the Supreme Court is currently deciding whether the whole thing even passes constitutional sniff tests.
Costco’s position is simple: Those tariffs cost the wholesale giant real money, the law doesn’t allow it, so … ahem … run them their money.
The Cult of Costco Rallies

As soon as the lawsuit hit the news cycle, Costco members took to Reddit to do what only Costco members can do: brag about insane deals while reaffirming their eternal loyalty.
One shopper kicked things off with what may as well be a campaign slogan: “God, I love this place. I bought a 77-inch LG TV and a 20-pack of underwear in the same trip and now this? Member for life.”
You know you’ve built a loyal customer base when suing the federal government becomes a perk on par with free samples.
Some members were practically drafting their Costco citizenship papers. One wrote: “I’m going to upgrade to an executive membership just to support them.”
Others praised Costco for keeping staples like bananas and pineapples at steady prices, even as tariffs hit.
Inside info was also strong in the thread, with one user commenting, “I used to work for one of their major brand partners and man… they fought for you guys. …They don’t play.”
“They don’t play” is an absolute mic drop here, guys.
Costco’s Brand Is Bulletproof

At the end of the day, the lawsuit might take months or years to resolve, but Costco’s reputation is ironclad.
They kept banana prices steady. They refund you after the sale. They’ll sell you a TV, a kayak, prescription glasses, rotisserie chicken, an industrial vat of peanut butter, and a treadmill all in one cart (okay, realistically that might take a few carts, but their devoted employees will bring them to your car for you!). And now they’re taking on federal tariff policy without flinching. And the people are pledging allegiance.
Because when your store sues the U.S. government and the top comment is basically “Wow, what a king, ” you’re not a retailer anymore. You’re a movement.
