The Adorable Costco Reusable Bags That Have Shoppers Singing, 'Let's All Go To The Lobby'

If there's one thing we've learned from Trader Joe's bag releases, it's that shoppers can go wild over a good reusable bag. Part of it is practicality and some of it is about signaling taste, but it also doesn't hurt when the bags are irresistibly cute. So, unsurprisingly, Costco's viral KeepCool character bags are flying off the shelves because of their adorable pattern, which reminds shoppers of a popular midcentury movie theater advertisement.

Decorated with a cast of anthropomorphic cartoon characters inspired by iconic Costco items, the bags feature everything from dancing membership cards to a whistling roll of Kirkland Signature toilet paper. But charming bathroom products aside, these totes have also been bringing back memories of an iconic 1957 trailer popularly known as "Let's All Go to the Lobby," in which a quartet of movie theater snacks encourage viewers to purchase refreshments with a catchy jingle.

Due to the striking resemblance, the folks over at r/Costco couldn't help but look at the bags and immediately start singing along. "When I saw that pic I immediately thought, 'Let's all go to the lobby, let's all go to the lobby, let's all go to the lobby and get ourselves a treat,'" as one person said. And of course, another Redditor had to give things a Costco twist by writing, "Let's all go to the food court."

Despite debuting in Canada last summer and making their way stateside around October 2025, these bags still remain an incredibly popular item amongst Costco customers.And it isn't just for their nostalgic appeal, as the totes are also well-made and super practical. They're washable and easy to fold, with reinforced handles and a built-in bottle holder on the inside. According to r/Costco members, they also have a sturdy bottom and are made of thick plastic, making them very durable and able to carry a lot of weight.

Perhaps just as important, though, is that they're roomy enough to hold your Costco-sized groceries. Unless you enjoy the challenge of trying to Tetris your groceries into an old produce box, one of the biggest Costco pro tips is to always bring your own reusable bag. These bags are a worthwhile invsetment based on that consideration alone and at less than $8 for a pack of four totes, they're also a great value. The only problem is that they keep selling out, so if you love a good tote and can't stop humming "Let's All Go to the Lobby," we'd suggest swooping up a pack now.
