Wandering the aisles of Costco can be a treasure hunt—bulk bargains, packed shelves, and a familiar in-house label that’s catching more eyes lately.

Longtime members have always known about it, but recent chatter suggests the appeal has grown beyond regulars.

From online discussions to word-of-mouth recommendations, these products are being praised for matching—or even outperforming—well-known labels.

The growing number of shoppers swearing they won’t go back to the old favorites is hard to ignore.


For decades, store brands were the underdogs of the grocery world—relegated to the bottom shelf and often dismissed as “generic.” But Kirkland Signature has flipped the script.

Costco’s in-house label is now synonymous with quality, value, and, in many cases, a taste that’s indistinguishable (or even superior) from the pricier competition.

What’s the secret? Costco’s buying power means it can partner with top manufacturers—sometimes even the very same ones behind your favorite name brands—to deliver premium products at a fraction of the cost.


Let’s break down the Kirkland products that have shoppers singing their praises—and why you might want to make the switch.
